Been checking my fuel mileage since I installed my 2nd hand motor and running 60-65 been getting 15.2 pretty regiously. (I need to up date my weight on my sig. but anyway I weigh around 11k.) Getting 14 pulling trailer 7k. My best was 16.3 driving 55-58. Now that is stock everything except 5" exhaust and BHAF.Today I put my DDP50hp injectors in and we'll see what it does. I now this eng. is a lot quieter. Next I will put EZ back on. I can say this stock s----

Yeah I would get the Edge hooked back up. It soon give you a slight boost to MPG numbers...

So it's the injectors that that make this VP44 24V rattle, huh, I wondered!I talked w/ a guy that uses his 2001 for his lawn mowing biz. He has his tuner box, paid $500 for it, I don't remember what brand, said he gets 30 set on eco mode. I don't know if he's full os S--- or not! No power tho! No mods just the box!Dave

Dave, No way... 30 mpg working the truck. He must be going by the lie-o-meter! (Overhead display is not adjustable if you run a box... it throws it off.) BTW, these trucks really should have had more gauges with the diesel option... pushing the limit (by adding a box) with no gauges is nuts. Running a truck "with just a box" and no supporting mods does not get the performance as well as not safe for the motor. But people do what they want with their own equipment. I would not.

my DAP 60's made my motor run much quieter all around, infact it is now about as loud as our 6.7.....(with the eb on that is:lol:I should say mpg went up too.
