I have yet to meet a guy with a 4x4 6.0 that has his speedo properly calibrated with hand calculations that can get 20 mpg. Especially on a bone stock truck. Not saying it isnt possible but that I have yet to meet someone that actually does.
Usually the speedos on our trucks (stock) are off by 1 or 2 mph and therefore dont record actual travel distance accurately. Meaning they display more miles than actually traveled and that coupled with the computer saying the truck is getting 21 mpg on a hwy trip basically invalidates any electronic mileage computations.
I guess whatever helps them sleep at night.
ya with my injectors the overhead reads 21mpg and 500+ till empty on a full tank... needless to say i wasnt shocked when i got 300 lol. Also with my wheels and tires the speedo is off by around 8ish (been milking that excuse for being pulled over for a while but gotten two tickets lately that didnt fall for that excuse) however the point of that was to prove that following GPS its more like 1.1 miles for ever 1 mile on the trip odo. Broken down by hand roughly 13-16.
I average about 13.5-14 mixed driving, but I have bigger turbo and injectors and a heavy right foot
however i drive like this guy
My average fuel consumption was 12.5 but I just put a bigger turbo and bigger injectors with a tuned FICM in so I don't know what that did to the mileage yet.
and probably like this guy as well... however i am interested in the miles with the FICM tuned as that is next on my list and possible strategy roll back to something more mileage friendly and no inductive heating
