    I still have my stock trans so I'm staying off 4 and 5 till I can afford a built one.

    I have a 2 wheel drive. I was getting 23 with the Quadzilla, and only 21 with the Edge on 5.

    I have a stock trans too

    History has always been the highest setting is best mileage. The #5 on the Edge is 100 HP and the Quad was 160. The edge smokes allot more than the quad did which shouldn't matter if you stay off it. But I lost MPG going to the Edge.

    He's running EFI. He should be able to do better. Who did the EFI tune for you? I strongly suggest you talk to the Terrorist

    Ryan Milliken does my EFI. With his reputation and knowing other people with his tuning I am sure it isn't the tuning causing the bad mileage

    With Ryans tuning I'm sure your fine. Boost leak usually won't cause this issue unless it's really bad (robs power but if it's small you won't notice it on mileage) injectors, sensory, or something up in the fuel system ie high pressure pump can cause it. If the engine is running of alot of duration and not pressure it will also lead to losses in efficiency. Sorry to scan through this what have you done thus far to diagnose the problem
