Well it been down right cold here today... Started my morning heading through New Meadows, ID at -2*F and travelled down to Ontario, OR for a few odds and ends supplies for back home. The average temp for the day was about +25*F roughly but then returning home and crossing New Meadows, ID again just before sunset at +12*F didn't reall get all that warm. (Brrr)...Now I will admit I high idled (6 Cylinder) to warm up the truck this morning and then kicked high idle back on anywhere we stopped keeping the truck cab warm. (Short stops). By the time we got to Ontario, OR wasn't too bad for weather so never used high idle again. IAT fooler is set at 143*F still... As for the Edge Comp I'm trying a smokeless tune (5x3) Which is full 120 HP but only 67% of stock fuel below 10 PSI of boost. Then on top of it I'm running my big heavy tires 265/75 R16's (85# a piece).Round trip 19.2 MPG and just the return leg I got 19.8 MPG. (ScanGauge II)Since I did two fillups from the same station at the same pump I double checked my ScanGauge II and it on the money... :thumbup2:So I'm tickled with the numbers even for winter fuels and winter cold temps!

nice!

what would that type of trip normally yield, MPG-wise?

Last summer with the lighter tires on 235/85 R16's @ 62# per tire and running Edge Comp on 5x5 I was getting 21-22 MPG easy. As for last winter I was barely making 20-21 MPG.
