I'm now a firm believer in a custom dyno tune! I took my 07 GT to Pro Dyno in Ft. Mill , SC near Charlotte, NC... I had a Brenspeed 93 mail order custom tune and don't get me wrong it was a great tune and the car run great... The ran 295 HP and 324 TQ not bad with the mods I have.( see below ) The car was running a little lean so Dan at Pro Dyno was able to tweek it and it pulled a 305 HP and 325 TQ! Now the car runs smoother and get even better gas mileage. Just thought I'd pass this along
It was $350.00 because I already had a SCT programmer. He downloaded the files on it as well...
