Maybe someone with a little more knowledge on this can weigh in because I can't seem to wrap my head around it. I'm looking for an aftermarket wastegate for purely astetic reasons. I don't want to change boost pressure or anything like that just yet but the kits I see come with 7 or 8 different springs. I guess my question is if I order one of these kits does a stock spring already come installed or would I switch over my stock spring from my wastegate? If anyone could give me any advice or point me in the right direction it would be much appreciated.
