I was chatting with a guy last night and he told me he had his truck on the dyno and was just shy of 800 hp. He then starts telling me "all" of his upgrades. He has a chip, stage one injectors intake and exhaust. I told him he was full of sh*t. His buddy told me he was there and it was the truth. Is this possible? I didn't think he could make 450 hp much less 800. Am I wrong?
