Hi have changed the ECU and am getting more power which is great but I think I am getting a fuel starvation problem. This only happens on the track. It will from time to time hesitate when excelerating hard But not all the time.
have any of you had a simular problem? if so did you change the pump?

Hey, i cant help you with your problem. But i think it will help others if you write which car model you are talking about. Supra or Yaris.
