fuel mileage 06 2500 6.0
#27
i just squeezed 320miles out of my tank... '01 2500HD, 6.0L, 5-speed, 4.10 gearing on 305/55/20 tires... not sure what size tank my truck has. i have read multiple places either 34 gallon or 38 gallon... also my tires are slightly larger, so my speedo/odo is off by a few mph.

I have 06 2500HD CC4x4 4:10, AEM CAI, Elec. fans, high flow cats, dual Borla muff, 265 tire16" alum., with 2klb welding Machine and tools on a flat bed. and I get around 14mpg on 93oct, tuned to the gills with my LM1 via HPT. Until I pull my 8klb. 32ft travel trailer do I get 11mpg.
Being able to control elec. fans via HPT, best mod I have made gaining over 1mpg, I also gained another mpg after installing and tuning for Hi flo Cats.
cheers
Chris

i have both knock sensor codes showing up right now, havent figured it out yet... it retards the timing and kills my mileage when under throttle. and also remember im running 33" tires as opposed to the stockish 31" tire...
