ive heard of people getting 19-21 mpg with chips and everything else done to there trucks and i believe there all liers!!!! i put a php 6 position chip in my truck and im only getting a maximum of 15 mpgs and thats hand calculated!!!!!!!!!!!!!!!

 

Hate to disappoint ya, 01 7.3 crew dually 4x4, 4.10 gears, swamps stage 1 injectors, tymar intake, 4" down pipe to 12" of 5" pipe no muffler, swamps tunes in a 6 pos TS chip, 18 MPG. Added the big wheel 22.5 kit with 255/70r22.5's and went to 21 MPG at 72MPH sweet spot.

 

Sure ya are... and I am getting 44 mpg... Its sweet...

13-18... thats about it. Anyone that tells you there getting more is a lowered 2wd standard cab...

 

in my pickup i get about 15-16 in mine. a friend had 2 that got around 18-19. one was a 95 2x4 xcab with 5sp and 4.10s the other was a 95 4x4 xcab with a 5sp and 3.55s.

 

I get 16 mpg, 17 going down hill with a tail wind.

 

I guess I'm a liar.

 

18.6 mpg is the best I've seen. Totally stock 01 4x4 6 speed straight piped with diy intake.

 

ive seen over 21 but that was a long trip of 65 with stock gears and 37's so at 65 i was doing like 1700 rpms..

 

Mines a 2000 with ts 6 chip, stage 2 injectors, hpop, meth inj, gtp38r turbo, cold air intake, afe intake manifold 33's tires and im getting 19.2 in the city i dont drive on the highway. I could only imagine on the highway. before i did the mods i was getting 23.6

 

Take the little overhead display, smash it with a hammer and learn to hand calculate...

Bet you would be very surprised...
