ok, so my girlfriends dad just bought a 2006 chevy duramax 6.6 turbo.....................i have a 1999 z28 6 speed with drag radials....he keeps on telling me he could keep in my rearview mirror and i just laughed it off but he was seriious i asked him what he had done and he said a bullydog chip and thats it...i said ok and we went to the highway and to my surprise i let him get the jump from 1st gear and i punched that SOB took off!!!! I punched it and kept with him in 2nd gear i immediately put 4 car lengths and kept on pulling when i hit third he stayed with me all the way to the end.....and get this! he just got the chip 3 days ago and says it has a 2 week break in period....he said he punched it and had to let off too 75 percent when he hit second cuz of a loud bang....turns out he messed up his transmission...was he lieing about the chip only or what?
