Hi all, a buddy of mine gave me his predator tuner that he originally had for his 02 Silverado. He put it back to stock and he has no more use for it. Now here is my question. I purchased my car used and it had the diablosport predator book in the trunk. I am unsure if wether or not it may have the tune in it or not. Will it harm my car if i try to reprogram it with his tuner? Also, any suggestions on settings and so forth for my car? I have full length headers, breathless performance intake, Magnaflow exhaust, cat delete.
