Ok guys here goes. Looking to get 400bhp from my S3 saloon 2016 all stock at the moment but I want to tune to this level with the best quality and have been told that ARP are about the best quality products out there. Been quoted for the following works intercooler, Cast downpipe, Carbone intake, Forge intake pipe, stage 2 remap, DSG remap, all ARP apart from intake pipe. Has anybody else had this done and was it the correct choice ??
