Ive got an APR dealer near me and am considering going Stage 1.. Firstly (probably been asked a million times before) how much difference is there from stock? Noticeably much quicker? And secondly would I be better off having it remapped with use of a rolling road? I dont think the dealer near me has one so am a bit wary of just tweaking it up and driving away without know that everything like fuel/air ratios etc are in line and not doing damage anywhere.
Thanks.
