Hi, quick question.
if an APY motor is 210bhp and a APX is 225, where does the extra 15bhp come from? the BAM and others are 225 but they have electronic VVT which would explain their extra power. is it a different map or are the cams different or something? if its the map i don't see why the S3's werent 225bhp from the start if Audi feel the engine is safe to do so (within their strict safety factors/emission regs)
