BlackbirdWS6

got everything put back together on my heads/cam car. got the exhaust done yesterday and such. anyway, I had the pcm sent out to ed wright for tuning and the car runs a little weird. I had them set my idle at 900, told them all the parts going in the car and the thing just wont decide where it wants to idle at. Most of the time is around 900, but sometimes decides to be happy at 1050-1100. While cruising with the car....it has a real quick hesitating/surging issue while cruising anywhere from idle to 2500 or so. However, when i romp on it, it has no problem taking right off like a bat out of hell. I checked the wires near the headers, plugs, everything else. dont kno what it is. any ideas? also, i have no SES light present.
