hello ive just got a nisstune ecu installed and tuned. ive had a highflow on the car for the past 5 months, and have had compressure surge problems from scratch. i thought we could make it better with a tune but no go
what it is doing is when i try and make booste bellow 3 grand in fifth, when ime over taking, it just goes into surge at about 5psi even on light throtle, it will do it in 4th at low rpm aswell.
if i go through the gears hard there is no problem.
i rang the place that did my turbo and they seem to think they put a t04b wheel in it, is that to big, would that cause this problem
its an r33 gtst s2
nistune
standard plumbback bov
14psi
