I recently bought an 08 GT with cams, full SLP exhaust w/x-pipe no cats or mufflers, JLT CAI, 30lb injectors, Steeda underdrive pulleys, and some kind of aftermarket rearend gear. Came with an SF3 Powerflash Programmer from Houston Performance., but noone I've been able to contact can give me any specs on what has been done to the car. I've contacted the former owner and the shop that did the mods, neither has any info or records since it was done back in 2008. What I do know I have figured out just by minimal car knowledge. I got a hell of a deal on the car and need to know how to program the timing into the flasher but I dont know how big the cams are or how to program the variable timing. PLEASE HELP ME! I can give additional info if needed.
