I'm getting tuned on Monday...just want to make sure I can make the drive 3.5 hours to Creech. Besides difficult idling...now I'm down to 12mpg and VERY sluggish. Is this a result of my cam, probably catless mids, and the computer being completely confused? Sounds like I'm way rich if my MPG is suffering that bad which would explain the sluggishness...right? This I would imagine is normal right? Looking for feedback ASAP.
