Hi everyone, I have a 2009 gti with stage 2 Driver motorsport tune, everything is stock on the car except a custom made de-cated downpipe, I have a boost fluctuation issue, my tuner said that it is the tune's overtorque/over-boost protection.
Here's whats happening:
sometimes at 4th, 5th and 6th gear if I WOT i get boost fluctuation which I am able to feel with car acceleration, the needle will fluctuate between 10 and 17 psi until i reach 5000 rpm where the fluctuation stops and boost is at 15psi which is normal for a k03, and sometimes if i wot at the same gear i get a spike to 23psi and steady boost at 21-22 psi.
This fluctuation is really annoying me, and I need your help to solve it, where should I start?
thx
Roy
