Hey all, I've an 2002 GT mostly stock. I do have a Flowmaster American Thunder cat back system with a BBK X pipe. Looking to get a flash tuner. Advice and sugestions would be welcome.

Skip the tuner, wont help much on a mostly stock GT. Get a plenum and throttle body kit, underdrive pulleys and a good catback exhaust or at least mufflers, those do help.

Get the tuner AFTER you get all the "boolt ons" then have the car Dyno Tuned to get the most out of the new parts.
