I have an apexi and 550s lexus afm 57 trim exhaust
got it tuned and the guy street tuned it and set the throttles at 10% low throttle
80% high throttle
when I wanna boost I have to floor it theres like this inbetween range in the pedal where if I barely press is like normal to just go or if I floor it its fine but this inbetween the car jerks and loses power and doesn't wanna boost but try's to.
is this becuase the throttle isn't set right on the apexi?
I've read before that it should be at like 68 and 69% or something like that
please let me know
