I have the edge comp box I was getting 12.5 around town before the box after 14.8 now the best setting for the box for me is 5 on 5 for mileage ,on the other settings I lose about .5 mpg go figure

5x5 for mpg increase? did you tap the pump wire?

yep sure did I just installed the new ip about 3000 miles ago used it for awhile without the tap had it on 3x5 for the 3000 wanted to make sure ip was good before tapping it for warranty since I tapped the last one warranty would not fix it when it puked even the old ip tapped I had better mileage on 5x5 and I did testing on all setting,I dont get it but I am not complaining

Well I have Van Aaken pnp and 275 injectors and at 11,300 lbs I got 30 miles to the Imperial gal. = 7.3 liters to the 100 km

TORQUE

Usually the overhead displays are slightly generous in their readings, especially when any type of fueling/timing box is added. A 5 or 6 spd is usually 2-3mpg better on hiway, than an auto.

When I had my VanAaken right from new, average mileage was about 22-23mpg imperial, now with my mods, I still average about 21-22 mpg hiway with an empty p/u box(hand calculated) but have a lot more power . I only ever broke 25mpg once, with a strong tailwind for over 500kms. The 12 valvers seem to beat us 24 valvers for mileage.

I have a 2003 245HP Auto Dodge diesel, HD 4x4 Quad, long bed. I made my own torque tube, and installed a Flo Thru 4 in. muffler. I went fron 20 mpg to 23.5 mpg. I used the on board computer for these results. I have an Edge Ez chip ordered and plan to set it on the 60Hp setting. Will let you know how it does. Javahjoeo from Kokomo

I am trying another super chips chip on perf-tow mode and I will let u know what happens. This is my second one ,due to the first one was bad and I sent it back . I lost 2 miles per gal .

Hey mr Javahojea. or however you spell it.

I have a pretty good idea what a 4" flo through exhause (or muffler is)? Isn't this just changing it all to a 4" straight pipe????

But the torque tube.....what in the world is that??? I don't believe I have heard that term before?
OK,

"Sounds like cummin's was forced NOT to have the optimum timing (usually when this happens it is due to US EPA smog reasons or rules about incomplete combustion and such)."

You are correct sir
