Fixed my ck engine light problem, still idling rough with ac on...

Ever since I installed my D1SC, my engine light has been on and Doug couldn't get it to go off when he tuned it. At the time he did not know that I could run two wires from the IAT to the MAF 6 pin harness which connects to the 4 pin MAF. He just told me I needed to convert to a draw through system and he could retune it a little better since he wasn't familiar with the blow thru systems. Marc did some research and found out about running the two wires. Anyway that is fixed and I did notice the choppy acceleration at slow speeds is alot better but the car still idles kind of rough with the ac on. Any idea how to fix that? I'm tired of people at the red lights saying "Damn boy that thingsa hittin' a lick aint it!"

sounds like the low end of the MAF curve may need a little tweaking
