I am after getting to the bottom of this. After having run Revo stage 1 and everything being fine, i went for stage 2 and had the dreaded misfire at 5-6k, after speaking to my tuner he said the rest of the exhaust sytem and or the HPFP will cure it (after ruling out the valve springs) , and it hasn't. I was wondering if those others are affected could either post up what cured their cars, or if they have the same promblem weather there is a common denominator? mine details are as follows
07 22k S3
Stage 2+ software
Autotech HPFP
RS4 Fuel pressure regulator v/v
THS intercooler
Denso Iridium IK24 plugs
Milltek TBE
EVOMS intake
Any input would be greatly recieved guys, as although its not as bad as the power surge felt at stage 2, after spending a lot of money (to me anyway!!) I'd like to find a cure
