Hi, I'm looking for some information regarding a slight hesitation that has just started with my 2010 S3. Car has done 11.5K. Mods on the car: ITG Intake, Autotech Fuel Pump, MV Sport Downpipe/Sports Cat, REVO Stage 2+. Car has had the mods since 2K miles and has run perfect up till now, the hesitation is lower down the revs with any kind of acceleration. (not clutch slip) If anyone has had any experience of this and knows what it could be could you pass on the information. Thanks in advance, Gary.
