I have a 2010 Audi S3 Sportback Stronic. I currently have software, 3" downpipe, Autotech HPFP and Forge twintake.
I am having a problem on the car that has been very difficult to solve.
Ever since the car was mapped, there is massive pull in the timing (Group 003) in VCDS between 3600rpm to 4200rpm in any gear (this is just as the car gets into boost). The car feels like there is a pause, and then starts accelerating again. It is highly frustrating. If I, however accelerate flat out (past the kick down switch), it is all fine, but when I accelerate from the WOT position at the kickdown switch, I get this hesitation. My tuner has tried loading different maps, but to no avail. The map on the car has worked perfectly fine on my friends (new spec) S3 which is manual.
I am hence very confused and have really been scratching my head. This problem really affects my day to day driving, as, as soon I gradually accelerate, I get the hesitation, which is really annoying.
Has anyone had anything similar, or could anyone share any light into this ?
