I Have An 02 Yukon W/ The 5.3l. I Purchased A Superchip Programmer, Registered It Online, And Tried To Prog. Programmer Said Not Stk Program. Took To A Shop I Work With Who Can Reflash Gm's. He Said It Has The Stk Prog That Should Be In It. He Erased And Reprogrammed Anyway And Still The Same. He Was In Contact W/ Superchips Regarding This. Has Any One Ever Had This Happen??
Thanks
