Tune question

My brother inlaw has an 05 GT with a C&L CAI and Brenspeed SCT 89 octane tune and he was wondering if the rpm's at idle at about 900 are normal. Also he is getting poorer gas mileage.

RE: Tune question

I never used the 89 tune, but I know the 93 drag tune Brent has is a little kick in the gas tank wallet for sure...then again I am constantly on it...

RE: Tune question

For the life of me, I don't know why these tunwers jack up the idle like that!. Especially w an auto there's few things more annoying that sitting at a light and your car is trying to pull away on you. When i ordered my tune from Brent I made sure to tell him to keep the stock idle speeds, which are 720 neutral, 650 drive (auto).
