..Chip this aint DIY never said it was...my other engine here is that...when this blows it will go back to being DIY....i cant help buying a saff with a mad engine..but as you say all modifications like installing turbo/plenum/plugging in chip /putting upgraded fuel lines in etc etc is DIY..mapping is for carol vodermans ..setting up will be diy though..and to be fair i will look at how it runs and tell karl if i feel anything needs changing...i guess a bit like say reyland...i dont beleive he maps..but has input like me
