I know the rev limiter needs to be dealt with, but does anybody use an aftermarket ECU or any other kind of ECU mods?
I dynoed my car this week, and the A/F mixture is all over the place (always lean). Seems like just boosting the fuel pressure will move the curve, but not change the shape much. How do I flatten it out?
