Cold air intake for performance and mileage?

Has anyone tried the Banks version of the Pedal Commander?? These seem to make sense to me in that these are drive by wire???

 

If it’s not adding boost, stay stock (or high quality air filter like a Wix) I’m a hot rodder thru and thru I’ve run everything from stroked motors, nitrous, blowers and turbos. These little 4.0 are built to last, not be fast, I love tinkering and adding speed parts… but…. Without adding a blower are changing gears, it’s not worth the money…. On these engines…. Mustangs, Camaros sure… just my $.02.
