So I finally got my new engine running and in my project truck and the fuel millage makes it undrivable, it's getting around 8 or less mpg and I don't know what's wrong.
Some background info, rebuild 7.3lT with factory turbo with ats hot side housing, 3" dp to 4" back, na pump turned up 2 flats, new standadyne G code injectors, timing is at 8*@2000rpm, electric fuel pump, R&D cam, 460 zf5, 4.10 gears and 33" tires, truck is a 4x4 crewab with a 2.5" leveling kit.
I'm not idling it at all, shifting at or below 2000rpm, not flooring it and not blowing black. I' not sure what to check for besides the obvious leaks or theft of fuel at night. So far I have driven 50km and burnt 1/4 tank
Any help is apprecated. Also I'm comparing this to my old tired 6.9 c6 3.55 regular cab 31" tires 2wd truck that got between 13-16 mpg summer city driving, i understand 4x4 and crewcab should be a bit less but not half the milege!
