im planning on ralling a gti with and uprated ecu, which one i havnt decided on yet. im after some advice on what the safe limit to rev a standard bottom end, ive seen posts on the cams which say that running cams would mean a need to uprate the pistons too so im hoing to get some gains from a mappable ecu? would this work? and what kind of gains would this bring???? cheers
