Audi S3 problems (newbie)
Im posting on behalf of my brother who currently has a 2003 Audi s3 (225bhp). The car has a front mount intercooler and a remap so should be around the 235hp mark if im correct?
As the car as it is when on boost it makes a whistle noise almost as if its coming from the turbo. He owned another s3 same shape (2003) without a front mount but was remapped. The current s3 seems to have less power almost as if its loosing power somewhere along the lines. Does anyone have an idea what could be causing this problem or does anybody know anyone who is willing to help. Im from Westyorkshire (huddersfield) if that helps.
Here's a snap of it next to a friends C63 AMG and an E46 M3 at Id-Workz;
