LS3 Corvette cam without a tune?
HCATK posted a topic in 1999-2013 Silverado & Sierra 1500I have a 2000 GMC Sierra 2wd ext cab with 134,000 miles on it. My buddy has a corvette that he just put a cam in, thus he has his stock cam. Would I be safe to put this cam in my truck without a tune? I want to put headers and some other mods on it before I get the tune, so it would be a month or two before I got it.
