Im having a problem with my greddy profec new controller.
ive got a r33 gtst s2.
Greddy fmic
fujitsubo turbo back
SARD Hiflow cat
Drift pod
cushion button clutch
Its over boosting every time i changed from 3rd to 4th gear. Car goes on 10.5 psi on 3rd gear and as soon as i changed to 4th gear while rpm is arund 6 or 7, boost increase fom 10.5 to 13.5 psi and suddenly drop back to 10.5 psi and hold it up there.
my settings
Set - 50%
gain - 20%
start - 0.6psi
warning - 13psi
limiter - 20%
Can anybody tell me why does it goes from 10.5 to 13.5 when i shifting on hi rpm ?
thanks
