Just to announce, I have finally gotten round to booking a remap for the a3 1.8t fsi sline. After much thought and torn between two providers I decided to go with the Shark remap so hope all works out and going by the reviews on here it's not too bad.
to add to it, Rob at CNTuning is fitting the uprated dump valve for me too (free fitting)
Thanks to being a forum member he was kind enough to give me discount too! Total price for all in was much cheaper than expected too.
