Okay. I have a 92 supra turbo that is stock except for k&n air filter and 3 inch turbo back exhaust with test pipe. Under good conditions, the air being dense, I hit fuel cut. I would like to buy an intercooler kit and turbo. I also really need help tuning the car. I was thinking SAFC. I have a greddy emanage but im not sure. Any help would be appreciated.
