2008 Pontiac G8 Gt Test

It didn't take long for the smack talking to start between Mike and an unnamed MM&FF member about which ride was faster: the new G8 GT or a new Mustang GT. A stock versus stock quarter-mile matchup was agreed upon. So, in the spirit of Jersey sportsmanship, we had Tune Time, which already has one of the country's fastest G8 GTs, install a custom tune. Using HP Tuners, Hauffe brought the timing up to 24, the air/fuel to 12.5, the shift points to 6,300, and the rev limiter to 6,500. Torque management was removed and the trans line pressure was brought up, the fans were set to come on at 190 degrees, and the top speed limiter was taken to an ambitious 200 mph. The tuned GT responded with 276 horses and 286 lb-ft, and we knew the trans/TM mods would yield big dividends.
