Force Performance in Yonkers, NY said they would do a custom SCT tune for my 05 GT as well as install my CAI and give me an XCalibrator 2 for $500. They will tune it on a dyno until they get the Air/Fuel and everything else right as well as get some decent power out of it. I am real new to tunes and wondering if this is a good price or should I shop around elsewhere. Please help.
