Ok, I just bought my first mustang. It's a 1994 5.0 5-speed. It's stock other than long tube headers, cold air kit, smog pump delete and the E-cam. I don't have any professional tuning equipment, so is there any way to tune it in my garage? I heard somewhere that you have to have a pro scanner to tune it through the computer. I don't want to do that if I can help it. It runs good, but it's way too rich and I need it to pass emissions.
