hey guys, I have a 98 Cobra with an SCT X3 handheld # 3000. It has a custom tune on it, which I want to tweak a little bit further. I can easily do this with my Jeep's Predator with a custom tune on it. Any advise????? thanks, Chuck The car/tune is close, I just want to adjust the timing a little and the fuel curve. any hints, or HOW to's ??????
