So I posted back in December that I was having trouble with mileage in my 01 3500, and 6 months later I still am. Engine load at 65-70 usually hangs out at around 32-35 if the ground is flat, and the way my tune is set up (just like what is recommended and also based off tunes you guys have made) I'll cruise at about 15* of timing. I've checked everything for drag and still have found not brakes dragging or anything. Bout the only thing maybe out of line, would be at idle after it's warm it'll stumble a bit, but it still maintains the 6-9% load, I even saw it at 12% with the AC on.

 

So anyways, would I do any damage by setting my load limit higher to maintain the desired 19-20* at 2k? I've gone through multiple tunes and like I said before, I can feel the changes in the way it drives but man it does not change economy at all, period, and I'm getting fed up and I'm about to go back to my smarty....

    Light throttle load limit is set at 25%. It's been a bit since I've messed with tuning and such since I just started driving a lot again since Rona hit, so I gotta relearn what everything does

    Will do! My plug for my rear diff speed sensor is broke on the pigtail, a long with a bad abs module, so I need to find a new pigtail or plug if you know where to snag one!

  • Unfortunately no. I’d check eBay though.

Man, you got me thinking a bit...

  • Injectors spray pattern poor or large droplets
  • Valve lash possibly affect the compression of the cylinder
  • Injection pump starting to fail
  • Excessive drag brakes, tire pressure low, etc.

-Valves were done, obviously I can do it again.

-Injection pump is not even 5 months old

-Wheels soon freely, even replaced the read ebrake cable in February and if anything the tires are too aired up.

 

I'm down to thinking it's injectors or my flatbed since it seems it would cause a lot of drag, but not as much as I'm seeing.

800, like Mike said. I probably should have specified, 12% load at idle with a/c on.

Maybe so for the readingly challenged as I appear to be. :doh:

Don't worry it's been a long day for us all.
