Ok, so you have intake, headers, exhaust, high flow cat, underdrive pulley, upgraded injectors, fuel pressure regulator, and cams? If you don't have ALL of these, ditch the 'chip' idea. When you call JWT to get an ECU, they will tell you the same for the simple fact that if you do not have all of that done, and you add something, you have to get an entirely different ECU.Moldingking321 wrote:Car is not stock and I still need a chip so what's good with that info
