what is actually needed for a k03s conversion on a mk3cupra? what would be worthwhile changing when doin it? i've got a samco tip, fmic n stage1 software and am about to do stage2 when the group buy on SeatCarClub comes about. i know its a fairly common upgrade but know its not just gonna be a case of k03 off, k03s on! also is it ok to run on stage 1software temporarily? discuss...!
