billybobby Posted June 22, 2008 Report Share Posted June 22, 2008 My buddy just got some headers, new mufflers and a tuner for his 99 GT stang. We just got done lifting and the first light we hit out of the gym red we both hit it No traction my truck has never spun so hard straight ahead. It didn't even seem like I moved till it shifted into second he pulled me off the line by about two I caught and passed him at 50. Next light we hit I put it in 4 high. Much different tale this time I left at about 2500 and chirped the tire's and left him for dead. I had never launched on pavement before in 4 high I was impressed it launched hard.

billybobby Posted June 23, 2008 Author Report Share Posted June 23, 2008 My drive train is all stock. The only change tranny wise is with the tune from Nelson changed my line pressure shifts allot harder. As far as power Nelson performance tunes trucks with the same mods I have all day long he says right around 450 to the wheels. I wouldn't worry about the tranny till it breaks I have 158,000 on the original tranny. Quote Link to comment Share on other sites More sharing options...

billybobby Posted June 24, 2008 Author Report Share Posted June 24, 2008 I know it's weak year for the Mustang. The truck has definently lost it's share of races but for a truck with stock internals it hangs with if not beats most stock sports cars. The tune from Nelson is what brought the truck to life. I bought it with the whipple tuner and had a small prob with it they Whipple recomended Nelson performance to me. Quote Link to comment Share on other sites More sharing options...
