YotaWerx Stryker dyno sheet

If anyone with the YotaWerx Stryker tune has dyno'd their vehicle, could you please post your dyno sheet? The only dyno results I've seen are the ones YotaWerx posted. A 3rd party's results would be helpful.

 

No dyno here, but I drove the magnuson tune then the Stryker tune. It’s massively different. For example:
The magnuson tune felt a bit weaker than stock unless you put your foot in the pedal. It tried it hardest not to boost and thus lots of people complain about how it’s a waste of money. Now it would easily go up hills and passing power was there but felt very abrupt since all other times it’s very muted.

the Stryker tune has instant acceleration right off the line with minimal input and the more you press it the faster it goes. Just seems much more natural for a supercharged engine. If you go to accelerate normally then push a bit harder it will just accelerate linearly instead of struggling then BAM Power. This make is more predictable and easier to control. And the shift points are far better than stock. Cruise works as it should without the gear hanging in 4th after going up a slight incline.

if you have a magnuson get it tuned; Stryker or OTT, you won’t regret it.

 

Go OTT, they know what they are doing and will be around to support you long term.

Looks like YW has went belly up. Thread here is locked and most of their tuning network is gone.

 

Maaan about a year ago I was hearing some rumors about yotawerx problems with newer models throwing codes and everything else... Very glad I went with OTT.

OP: I'm not supercharged but my experience with OTT was top notch.

Here's their thread.

Welcome from Arizona!
I have an OTT tune that works well.

 

They have dealers all over and are actively tuning. Why would you assume they went belly up? FYI I have the Stryker tune and it has no issues. I may go OTT one day just to compare but the requirement of a fuel pump means I’ll wait.

 

Thanks for everyone's replies.

I am very specifically asking for _objective_ dyno results rather than subjective experience. My observation has been there are literally no independent, 3rd party dyno results to support YotaWerx Stryker tune. If anything, the OTT "truth be told" dyno results for YotaWerx non-Stryker tunes yield skepticism (Google OTT truth be told). Moreover, if one studies the Stryker tune dyno and compares the gains against the OTT tune or simply compares the gains from stock vs Magnuson supercharger w/ Magnuson tune, common sense may yield one to reasonably question, 'is YotaWerx really getting almost 2x the torque gain at 4k RPM than the OTT tune did?' (and yes, I'm familiar with how dyno results may vary based on altitude, temp, and the particular dyno) The most reasonable way I see of settling that question is with independent dyno testing - which is why I am soliciting the forum collective for that dyno data.

In the absence of independent dyno data, one has to evaluate based on other factors. I don't consider the subjective, 'it made a big difference' input to carry much weight. People say the same about a pedal commander. One factor I see a lack of technical dialogue from YotaWerx to support that the tune isn't a hairs width from grenading the motor after 50 - 100k miles. If that happens after the tune, it's the owner's very expensive problem. I've little doubt any tuner makes the customer waiver all liability of such problem. When I dig into discussion from OTT, I do see more technical insight. I don't expect anyone to give away the details of their tuning philosophy and the raw data that goes into it, but it seems appropriate for a tuner to put forth more effort than, 'we've a lot of vehicles tuned with this,' or 'it's a safe, conservative tune.' Those are just words - not proof. When someone stands to gain money, I view language like, 'it's a safe, conservative tune' as salesmanship rather than proof of technical competence.

My own research has led me to be skeptical of YotaWerx dyno sheets and business as a whole. Frankly, I think Christian (owner, not a tuner) was outright lying to me in communication I had with him where he was 1-2 months delayed in responding, but perhaps I'm wrong. The fact that their tune developers have left at different times in 2024 means something was up. I've also heard negative feedback about one tuner. Regardless, that's all hearsay and speculation. They might be competent tuners, but I don't have objective results nor deeply technical discussion to give me confidence. Personally, I only see salesmanship and subjective support. When it comes to the money involved and the consequences of a poor tune, I need more than that.

 

If you stop and think about it, why would the YotaWerx Stryker dyno show quite a bit more torque and power than the OTT tune but not require a higher flow fuel pump? Isn't more fuel needed for more horsepower? Afterall, the URD Whipplecharger makes comparable power and includes a 7th injector and bigger fuel pump.

I wouldn't be surprised if the Stryker tune is starting to run lean. Perhaps the tune developer(s) are only tuning at higher altitude or with vehicles with clean fuel filters, or perhaps the YW tune developer(s) are seeing the engine leaning out and not disclosing. Perhaps Justin @ OTT is competent enough to recognize the signs of a struggling fuel pump and honest enough to point it out (link below). Granted, I'm speculating about YW, but anyone reading this can consider my logic and evaluate for oneself.

Easy, tuning. Some tuners like to go with lower torque and higher hp at high rpm. This method is “safer” but more importantly it won’t have instant torque when you press the throttle leading to a smoother (more linear) feel. You only need more fuel for high rpm’s or more boost. Look at any turbo applications dynos high torque but falls flat at 5k rpm, now throw on a fuel pump (and possibly larger injectors) and now you can feed it enough to have power all the way through the rpm range.

I have owned and tuned turbo/supercharger applications for over 20 years and have personally tuned many vehicles as well as purchased off the shelf tunes. As long as the air/fuel ratio is in tact and knock is controlled you are safe. The Stryker tune is safe just like the OTT tune is safe, many people have tested them and reported on the findings.

 

Because all their “calibrators” have left the company. If you go back to the performance page you’ll see a “new” tune from their final calibrator to leave. Word on the street, anonymous sources confirmed…

if it is such a great product, why the splintering of the network and silence from YW?

 

You sir, seem like a very smart individual with critical thinking skills.

 

A measured plot of knock, timing, and AFR/lambda on a WOT to high RPM run at close to sea level with colder air temp (denser air) would help provide objective support for the assertion the Stryker tune is safe. By "safe", I mean isn't running lean due to the fuel pump struggling to meet demand. It wouldn't necessarily, however, address what happens as a fuel filter's flow reduces over time/use.

 

All dyno data can only be compared to itself on the exact vehicle. The Yotawerks dyno was on a vehicle with 33s and very heavy. You won’t believe anything anyone posts anyway. Best option is talk to Christian and get the tune with the understanding that if you aren’t t satisfied you want you money back. The. Dyno it before you tune and directly after.

I have driven the magnuson tune and the YotaWerx tune, one day I’ll drive the OTT tune. That said. The power difference and drivability differences are massive! I’m sure the OTT is massive as well from the magnuson tune. But the OTT and the yotawerks have very similar peak hp and the yotawerks just has more torque which is easy to obtain at those rpm’s with the stock pump.

if you want a more linear power curve and slightly higher hp then go OTT. If you care more about low rpm torque and slightly less top end power then go YotaWerx. Both are great I’m sure and both as massively better than the magnuson tune.

 

Ask Christian at YotaWerx to provide this if you want. Otherwise that will be difficult to come by unless you want to buy all the sensors and software yourself.

 

You can get this from a proper data log without external sensors. OTT tuners capture that data as part of the tuning process and logs are reviewed and verified, adjustments are made as needed on every forced induction application.

 

It’s not on their website. Either one. I don’t have a data logger anymore. But I’ve seen post about this, they are difficult to find but do exist. Again, you can buy the tube a log or reach out and ask. But zero issues from any person that has the tune so that says something as well.

 

Here is a screenshot of an OTT data log on a 2018 Magnuson SC T4R at WOT (100% throttle, 100% load).

Lambda is 0.813, 14.6 x 0.813 = 11.9 AFR. If you want it on a dyno chart that can be obtained as well. Need to hide some values to protect IP.

 

Fundamentally, this thread is about providing objective (and ideally independent) data to help 4Runner owners better make tuning decisions. Posting a dyno chart along with altitude and temp is helpful regardless of whether it's from OTT or YW.

Regarding your data log picture, stating what altitude (or city name) it's at and whether the fuel pump is stock or a 255+ LPH is also helpful. Thanks!

 

There seems to be more information on the Tacoma boards. I found this, it may help. Last post talks about air fuel and knock. But again on Tacoma. https://www.tacomaworld.com/threads/magnuson-supercharger-tunes-yotawerx-and-ott.837765/

I live in Bangor Maine so if anyone has a data logger wants to meet up I’d gladly do some pulls.

 

I'm going to send you a PM regarding the logger.

 

A customer pinned me on this convo, so I would like to clarify some points and add a few remarks.

I am Christian, owner of YotaWerx.
First and foremost, thank you to all the YotaWerx customers and supporters. We would not be where we are without you & your honest feedback.

Regarding the 5th SC tune. That was actually developed by me, in collaboration with my former business partner and a tech we had as a partner. I was operating the dyno and we were doing adjustments as a team. Before we reached that point, we had been on the dyno multiple times and I had personally pressure tested/developed the tune on my 4Runner with a Maggie. This is standard for all the tunes I offer - the tune is first developed on my own vehicle and I then reach out to a network of testers for feedback. This occurs months before the tune is available to my network of dealers and customers.

The information posted on that dyno day is missing the following: Dyno numbers for the final tune, performed in San Jose, California at TPS MotorSports Dyno, one of our dealers.

The time of day was 2 p.m., and it was 94 degrees, so a hot day.

4Runner was a TRD pro, 2023 with 285s on Stock Wheels.

Dyno pull was done on 3rd gear, with the tune allowing for gear lock.

After testing for a few hours, we determined it was successful and cleared it for final numbers. We ran multiple tests and, on occasion, we actually made more HP than TQ at different RPM ranges with different tunes.
As always, we strive to make more TQ than power in the lower RPM range for usable power. Only a few people push these engines at high RPMs, and those who do so, only do it rarely as it is not a dedicated 4x4 vehicle. So there’s no point in making peak power up high in the RPM.
These are not race cars. Anyone can make high numbers, but getting good numbers reliably is what makes a good tune.

———————————-

With regard to the comments about me not being a tuner, you’re mistaken. If I never made public my ability to develop, it was because I supported my team and their work. Rather than stepping on their toes, I trusted their efforts and helped them overcome challenges.

My role was, and still is, operating the business and making sure the team has the tools they need. In other words, I work on the business, not in the business. All SC tunes for Tundras, 3rd Gen Tundra, the GR86, GR Corolla and all the new updates have been completed by me, not a former team member. This includes all custom tunes, which YotaWerx is now offering and customers can schedule with me during a dyno session.

My tuning background starts in carburetors as a kid, then as an enthusiast in the VW/Audi/BMW/Porsche world. I later jumped to newer Toyotas. My last Audi was a Mk2 TTRS pushing a reliable 540whp, and my last BMW was a 335d making 480whp and 689wtq, giving me 32MPG. I eventually traded in the Audi for my 1st 3rd Gen Tacoma, which opened the door to the tuning world I am a part of now.
I have owned multiple vehicles that never end up in the public eye, and you probably see more of me in my motorcycle world. I’m a dirt bike fanatic & ride 2 wheels in an Enduro style a lot more now.

I am not a salesman, but honesty goes a long way. So, naturally, being passionate and enthusiastic about my product is good for business. I am true to my core, and I am just another person who enjoys working on cars, bikes, trucks, airplanes, guns, house projects etc.

Lastly, I do have a professional degree, and it has nothing to do with cars. Hope the info provides clarity.

As of YotaWerx. We stand HIGH and proud. Being a part of the community at this level is pure enjoyment. I get to have fun in what I do for a living.

 

Now for the fun and giggles. I am not wanting to be combative.

1. Your post is the 1st comment on your profile. Which is kinda of odd, and is a very similar behavior to things I see every now and then, but I might be wrong. Yet, your style of writing strikes me familiar.

2. I did have a customer reach out over timing of a tune that is actually not even related to this generation of 4Runner or engine. Who spoke about availability of the 2 months eta, I had provided and it came a few months after. That tune is the Kline 03-04 4.7 4Runner and GX470. That is now live and ready for customers to purchase. So your approach is odd in general. Yet, I did speak about making updates to this SC tune. Which are coming up soon. So you might one of the few I spoke to.

3. It is known that my competitors play these games and it’s just not even surprising anymore. Fake profiles, misleading information etc. I call them out every now and then. Just annoying to deal with. Yet, they are not tuners they are just sales guys who know how to perform a flash procedure and data log. Those are just the guys who make the noise, the owner is actually quiet and I respect that and understand it. Just not my style of doing business. Your sales reps are an extension of you and they also represent the business.

4. If you are interested in getting a tune reach out. I am more than happy to guide you through everything and help answer any thoughts you might have.

5. I have and old profile here probably from 2012-14? Don’t remember accurately. On an old email that got hacked. Haha, so pardon my new login.

I have used the treads for all my builds and absolutely love the info on the forums. I just have never been active on here. Now, with the business being public and not having a rep for forums, you will see a lot more of my day workings with mods or fixes.


That’s all being said. Peace and don’t cut off a finger when tooling.

 

Haters gon hate, so let em. Carry on smartly, as you are.

 

Just met up with Allan at Master Yota Tuning http://masteryotallc.com/ and installed the OTT tune with the mild throttle response. I am going to drive a few hundred miles and will start a new thread on a detailed comparison of the three tunes; Stryker +, Stryker, and OTT.

Allan was extremely professional and proud of the product. He provided a full service approach that included cleaning sensors (just in case due to an oil based filter being used) applied the tune and went on a test drive with me while datalogging. He also has a really great mobile setup to fix anything that may go wrong (even with extra ECUs on hand for Tacomas should the need arise!).

I will provide as much detail as possible. I will take the 4Runner in every situation on road and off road that I have also taken the two Stryker tunes in. Full disclosure I paid for the Stryker tunes and the OTT was given for free so that I can provide an unbiased opinion of the tunes but I am not being paid for this or pressured to lean one way or the other.

 

Here is my review link. I will update with more info on this one when I have driven off-road with the OTT tune
