You don't need any "supporting mods". That largely doesn't exist anymore.Hey there, I'm looking into getting the race chip myself, but am worried about my car since its stock, there's no supporting mods yet. I'm not familiar with modding cars and what the limitations are so I was worried putting in a chip tune might blow something out if I don't have other things in the car upgraded. That said, When you installed your race chip was your forte gt stock?
Get whatever device tickles your fancy. 20-25 whp gain, 30-40 lbs of torque on 91/93
Bench flash (Sixth Element,Tork Motorsport, etc) will adjust the fuel (it runs really rich after 4500 rpm) and run more boost before overboost kicks in and closes the throttle.
That will result in more power but is more evasive. Piggybacks are fine for mild power increases. If you want a little more power you can mix in octane concentrate like Klotz, Boostane and VP Octanium or a couple of gallons of E85 with your premium pump fuel (E20).
