i have a 07 GT/CS looking at doing tunes what do you suggest???

 

Depends upon what your looking to do. But i'd check out Delta Force Tunes or Brenspeed Tunes. Both are pretty good.

Or depending upon where your located at and what types of tuners local dyno shops use. Buy a device that a local shop dyno's with would be my advice.

 

We have multiple options for the 2007 GTs, check out the Predator or Trinity!
