This is a tune that came in the 97 Saleen coyote swapped mustang with a FRPP control pack. Has a Gen1 coyote motor/TKO600. Maybe I didn't see something in the tune, but with the AC on it drops rpms pretty bad where it almost dies whenever you push in the clutch when coming to a stop. It idles fine with the a/c on. Please let me know what I am missing. I added more airflow at idle, but that didn't fix the problem. Still new at tuning fords. Any input will be appreciated.
