I have a quick question to a problem I can't seem to fix.

I have efilive and am tuning a 2002 z28, 383, heads and cam. Auto with 2900 stall. COS3.

I have everything working great and the afr is dead on. The only problem is that when I turn the ac on in P/N the idle will surge up and down and then sometimes die. The ac clutch will kick off at about 750 as it comes down and then kick back on when the idle surges back up. The ac is charged and blows cold. I can hold my foot on the gass a little and help the car calm down into a nice 950RPM idle with ac on and then it idles fine until disturbed. If i put the car into gear, it will surge bad enough to kill the car fast. The car works great with the ac off and has no idle or surge problems. Please help! this is my wifes car and you know how that is.

I attached my tune to look at.

I'll take a look at it when I get home (no tuning software here)... simple fix by adding air to the A/C tables under idle.

Thank you a million. It is dead on now. Also, the car seems to run better in all areas of the map. The wife will be very happy now and I might get lucky.
