My cousin has an 05 F-350 turbo diesel lifted with 35" AT's and a chip. He swore he would beat my gtp. I didn't think he stood a chance but I finally gave in and raced him. Needless to say I won by a few car lengths. Now he claims he would have beat me with stock tires on. Anybody agree with him? We really can't test that theory since he no longer has the stock tires.
