Since the day I picked up my 2005 GT from the dealer I have been looking at changing the factory tune. This weekend I picked up my
SCT X-Calibator 2 from
Wide Open Throttle Performance (WOT) in Riverside Ca..
I had two tunes made and programed into the tuner. Pete the owner at WOT made some adjustments to the SCT program for spark timing due to the fact that the gasoline in CA is junk and the timing SCT has will cause pinging
. The down load into the cars ecm was a snap. The performance of the engine is great now that the throttle is faster. The tuner also changed the shift patterns on my automatic. The 1-2 shift is longer and 3rd gear holds for some time under load. It has made driving the car all the better and I cant wait to take it to the track this coming Sat. I plan on going back to WOT and have a dyno done so that i can see what improvments the tuner has made over the stock tune. The cost for the tuner and 2 programs with tax came to $400.00 www.wotperformance.com
