Am I the only poor SOB BARELY cracking 10 MPG's using the extreme race tune? ON THE HIGHWAY!

[scoobywrx05]

On xtreme race I get 16.5 ,,,,,3.73 gears with 35 inch tires and auto tranny....70 mph up and down moderate hills.

[Floridayfz450]

So that's around 500 miles a tank on a shortbed correct? I'm BARELY getting to 300, and that's with filling 32 gallons into the tank. Average was 450 miles per tank with the canned SCT extreme tune.

dont go only by the lie o meter, hand calculate for bet results.

Also, if you have larger tires, and your speedo isn't adjusted, make sure you compensate for miles shown vs. actual miles driven, prior to figuring MPG

I'm going by Miles per tank, I reset the meter every fill-up. My speedo is adjusted to my tire size as well.

what did you use to calibrate the speedo?

The SCT user options while loading the tune, this works right?

[Abrannan19]

no, unless something is different for the 08^ the SCT cannot calibrate from larger tires and adjust the speedo, it will allow you to enter revs and tire size but that just adjust shift points.

What size tires are you running?

[scoobywrx05]

No,,,that doesn't actually correct the speedo,,,it is to tell your tranny to shift at different points to accommodate your bigger tires...
