I have a 2005 mustang gt that I've owned for about 2 months. The car has a Paxton Novi supercharger installed, and it was controlled by a Diablo tuner with a "custom" tune downloaded to it from the previous owner. After leaving a red light (in first gear) the car lost all power and went into "engine failsafe mode" we took the car to my personal mechanic, he couldn't do much due to the supercharger and other mods on the car. We were able to drive the car to a local performance shop to see what they could do. He explained that Diablo tuners are old technology and it would run me 400 dollars for a new tuner and another 600 for him to program it. This is in addition to the money I've already spent for him to run diagnostics, change the spark plugs, and cut the cats out that were believed to be melted. Does anyone have a suggestion as to what rout we should go. What brand of tuner and what shop. Im looking for someone reputable in the south Texas area, San Antonio and Austin are my first two choices as to where to take the car.
