Ok... Ive had my adrenaline since june and have played with a lot of different tunes trying to get better fuel mileage... but I cant. I have a 5spd with 4:11's and 235/85-16's. I commute to school and work everyday which is 35 miles round trip. About half is highway, the other half is country road.... best average mileage to date is 15.5 running the comp tune on 5 and staying out of it. Has anyone come up with any tunes to help get better fuel mileage? Or is there maybe something else wrong? I change my oil and filters and fuel filters every 5000 miles. Any help would be greatly appreciated.

 

the 5 speed 4.11 combo kills you on the highway unless you keep it under 60

 

looks like im gonna have to go to 315/75's

 

drop down to 3.73 or 3.54.

Set your timing on the Pulse to 10. That seems to make the biggest difference on mine.

 

19 mpg w/ the torque tune on PL 8, auto trans, 4.10's and 285 70 17's

 

Around town, the torq tune does do pretty well, but my truck wont run up the freeway with it...

Anything above 70 mph and i have to play with the throttle to keep it from shudering and breaking up.

 

Just a little side note... i loaded up the new comp tune last night and ran it this morning and the thing actually fuels pretty hard all the way to 3800... I was surprised

 

I am looking for a good tune for fuel mileage. I am currently getting 17mpg, and feel that is should be a little higher. I could be the tune that I am running, I have done everything else said to help MPG’s (IAT, MAP, APPS, Air Filer, Fuel Filter) Here are the numbers for the tune that I am running, tell me what you think tweaking might help out.

Power Levels: 11
Timing: 8.0
Timing Scale: 100
Max Pump Stretch: 1400
TPS Pump Max: 100
TPS Pump Min: 30
TPS CAN Max: 100
TPS CAN Min: 30
Boost Scale: 38

That’s the tune I run all the time, usually on level 0. The pulse monitor used to remember what level I left it on last, but since I updated the software, it always defaults to 0; does anyone know how to fix that? Jeremy told me that level 1, was there “Mileage Max”.

Also does loading other tunes, change anything besides those numbers? I think those numbers are a 1000 tune

 

Bump the Timing up to 10. I get the best mileage with the Pulse on level 5 or 6 as long as you can keep your foot out of it
