I've got some spark knocking going on at high gear, low RPM. Running premium fuel, so my goal is to just have the engine run a little more rich. I can't afford the 7th injector kit plus all the labor, so i'm pretty set on the tuner.
Anyone know what tuner to use? Just need to adjust fuel air ratio.
