Got my tune a month or so ago and after going back and forth with Jeff, we got it doing fairly well. Had an airaid installed but previous owner did the "mod" to the inlet of the housing and it was causing problems with the tune. No matter what SVC did, it kept throwing a code for too much air or not enough air. Put the stock intake housing back on and got another tune from them and so far all seems well.
Coming from the diesel world, the tune didn't add as much power as it really helps with the driveability. So far I'm happy with it. Wish i could have gotten the intake to work with the tune, as i liked the sound and even got an extra MPG with it on.
