whats up people! installed r38 update on u7140 and used the airaid tune. the car is working great,wow what a difference!!!! but it seems like when i lift on the throttle a lilttle bit it pulls better. could the air fuel mix be off a littlle at w.o.t. ? i am planning to put the car on a dyno a.s.a.p. was wondering if anyone had any thoughts on this.
