The Mustang Gt is kinda the fun car to beat on for all 1g mx6 GT.. 'stang owners like to pretend they have a 5.0.. but they don't.
The fun part is, if you chip your gt, and up the boost to around 15 psi, you can just about do the same thing to a Mustang 5.0...
depends on the year of course.. but.. still.. that's what makes the 1g MX6 so much fun.
