You need to check the return rate of the injectors. The short version is take lose the return line run the truck for 15sec. and measure the fuel that came out of the line. If its more them 20ml then you have bad injectors.

At 230k you could easily be do for injectors. How is your RP holding and at what PW?

This is from my memory so bare with me.

Stock tires with a exhaust and quadzilla tuner. 21 mpg

33's on stock rims with the same performance mods done. 19 mpg

33's on 18" wheels. EFI live, egr delete and CAI. 17-18 mpg.

Alright ill look into it. Im guessing this should be done at operating temp? Ill do a search on it. But yea with my setup looks like im about right in there with mpg. Truck runs too good to need injectors i think. But ill check it out

My truck still ran great too, but had a strong fuel smell and got horrible MPG while even towing my rzr around. Never any white smoke either.

Didn't read all the posts but my I took a road trip in my built motor LMM. 14 hours of driving and I got 19.2 mpg. I'm running marks tunes and have zero complaints.
