Hello everyone, After a bit of lurking I thought I would make my first post. I recently bought my first audi, a 58 s line a3 sportback in red with a 140 CR engine. I've got the day off tomorrow so will upload photos of what I've done so far to the car. Ive had the dpf removed and remapped. I spoke to the guys who did it and they say that they couldnt do before and after dyno's because the common rail engines didnt play nice with the rolling road. This makes no sense to me, surely the result is based from power produced at the wheel hence the engine shouldnt matter, could anyone shed any light on the subject??
