It's my first time tuning a cammed car and everything is going pretty smoothly. Its a 02 z28, with a tr224, most boltons, and a 3600 edge converter. The only problem im havin the rpms go to 13-1400 when putting the car in drive or reverse. After I press the brake it goes back to 750 rpms like its suppose to. It will pull itself like this until you come to a complete stop. Any tips or suggestions?
