With my current set up (E-rated 275/70R17s, slight lift), I'm averaging only around 15 on the highway.
It's all very dependent on wind and speed. A few months back I was driving across New Mexico with boxes on my rack and into a stiff headwind. I got a jaw-dropping 8 mpg for a stretch.
Just picked up a Sprint booster, from what I read it seems it could help. I'm desperate!That's strange. I also have an AFE CAI, but your tire size should equal better mileage. However, if your KO2's are E load they are very heavy and "may" be a factor. I got rid of my E load KO2's for the C load Ridge Grapplers and wish I would of started with them.
I also have a Sprint Booster, which depending on how you drive, can improve overall mileage, but just by a little. Maybe that's the trick... but who knows.
As usual, I reset the on board MPG meter at the gas station. Pulled out of the gas station on an empty road with a slight down hill. When I crossed the bridge the MPG meter read 27.2 mpg. :girl:
Alas, when I got home, it was back to it's usual 18.7 mpg.
