I am stage 2 cobb right now and I get 26 - 30 Highway cruising and 20 - 24, driving it like I stole it. Something is way wrong. I aint sure what it would be, I would think it would run like crap and smoke like a diesel if it was so rich it gets HALF the mileage.

so how much gas are you putting back in it? are you using the miles/gallons to get your mpg?? if you are, and still only getting 10, then something is really wrong. my car was getting some crappy mgp for a while, but it went back to normal. running a stage 2 and still getting 20 city, and about 28 hwy. how many miles are on your car? tune up recently??

How are you measuring it?
If you have a spreadsheet that is calculating long-term numbers then you have a problem.
If you're saying to yourself..."OK, 1/4 tank = 40 miles so a whole tank is only 160 miles...divide that by the size of the tank..." then your logic is flawed.
