my lift and tires dropped me 3 mpg before superchips. I am constantly checking it and i would say at this point flashpaq got me back 1+. Additionally any lights which are not directly in front of your grill are going to drag your milage down. my lights on the windshield are prob costing me 1 mpg. When i had them on the roof of my ZJ they cost me 3mpg. The rediculously large sideview mirrors prob account for some mpg loss as well. A lift by itself will in fact cause a loss in milleage. As you raise the vehicle the suspension and drive train stays attached to the road and thus the frontal area is still restricted to smooth air flow. A moderate lift and 33-35" tires will cost you at least 2mpg but more likely 3 (depending on 2 or 4 door etc. i have got as much as 58mpg also, but that was driving down a 8% grade for 3 miles in nuetral. Do not believe the hype your milleage will suffer.

 

this is funny, I would probably get one too!!!
