I have a stock 3500 with a 6.0, reg. cab (no dual rear). I want to start turning mildly, and as cheap as possible. Only keeping it another year. Where do I begin. Always hated the TM. Is there a simple way to to deactivate it. I don't tow or plow. Also do I just buy a proper OBD2 connection cable and use services (EFI LIVE, LS ADDICTS, BLACK BEAR), or should I buy a handheld? Also what should I buy?
