my last freeway trip empty rolling 80 was 18.75 hand calculated juice on 3x3

 

ive got mine set on 1x4 right now, but i havent tried the rest, ill try 3x4 or 4x4 and see how that works on the next tank.

 

My old truck got better mileage with the comp on 4X5 than any other setting

 

Luke,
I'm wondering what injectors you had in there then? My problem is is I set it like Mopar has said I get way too much smoke.

 

Like my sig says,got 23mpg over 750 miles of freeway,just had to keep it around 60...it was a yawnfest,but 5mpg makes a difference...

 

ive got the same problem, in level 4, i smoke like crazy if i barely touch the pedal, but im staying in level 4 to see if it helps. also i found plugging the truck in while parks(even in the summer) i get much better mileage, upwards of 2mpg gain!.

 

I'm still stock and use to get 18 to 19 MPG on the road, since I put a topper on it I can't get over 15 mpg, I use to get 14 mpg pulling a 16ft foot trailer with 8000 pounds in it at 70 mph.

Seems to be running fine, but haven't pulled a heavy load in a long time, but I have been in the mountains, I figured I should have worked it enough, maybe I need to grab my brother travel trailer and pull it up the road for a few hours to clean it up.

 

So what should a almost stock 98.5 RAM 2500 Laramie XLT 2wd with 4" exhaust auto trans,5.9 24v,Club cab, get in MPG ?

 

I get anywhere from 20-23 MPG. Mine is a 00 2500 2wd QCLB. Way better than what I got out of my Z71.

 

You should probably see around 20 with everything stock. I have 33" tires and on a long trip I can average 27 depending how I drive.
