Is there any turbo gurus on here that would mind if I called them and asked some questions on my custom turbo ls1 conversion I am doing in an old 72 gmc Jimmy. I have done hours of searching but can't quite get all the answers I am looking for. I am running a turbonetics t-61 with a rg-45 wastegate. I am installing 42lb injectors, valve springs, rodbolts,stock cam for now (ls6 down the road). I would like to know how many o2 bungs I need to intall, I have a weeded down factory harness and computer. I am shooting for about 500hp, reliable daily driver. What tuner is a good start and what tune is safe? Any help is appreciated. PM me your number if you don't mind thanks Peter
