I met one of my somewhat old firends I see sometimes and ran into him at an autozone and he has this 05,06 5.3 chevy 1500. with an intake and exhaust. just muffler swap I think. And asked me around how much hp and tq I have but I havent done a dyno so I didnt know so I just told him what I had done to my titan which is a few more things than he has done to his chebby. and he said that he"ll be able to keep up with me or be right behind me and if not beat me soon if we'd race.I just wanted to laugh. and tell him even a stock titan would beat him with his intake and muffler swap he had. By the way he also had 22's.
