pretty reserved. I used to drive it pretty hardcore, but for the past 2 or 3 months, ive babied it. I just can figure it out. I dont have a heavy foot. It does still have to be retuned, but to drop that much is alot!

Make sure your tune is setup so you aren't running constantly in open loop. You'll have to ask your tuner to make sure he put it back into closed loop enable. Also ask him about the gas mileage, since I'm pretty certain it is PCM related.
I have an MS3 that was untuned (super rich), running open loop, and getting similar mileage.
