I have a 02 that i just bought with an Edge Attitude. It must be a pretty old tuner cuz i think its only 75 horse in level 5 and i dont see anywhere on it to check DTCs (diagnostic trouble codes). When i accelerate pretty hard i get a check engine light but it must be a soft code cuz it goes off when i cycle the key and sometimes it goes off on its own. Sometimes it comes on with moderate acceleration. Anyone have this problem. I have an aftermarket intake,4 inch exhaust,aftermarket turbo wheel and aftermarket torque converter and tranny work.
