Gas Mileage after Programmer

[RippSpeed]

Ok an update...
I recently switched over to Royal Purple synthetic 5w30 oil and change to a PureOne oil filter... reset my avg mileage on my DIC, filled up on gas and re-loaded my Hypertech program... So far on this tank I got an average of 12.4mpg the highest showed 16mpg on my DIC ... But I know its not rock solid yet ... I'll see how she fairs when I take my trip to San Francisco... I'll post my data on monday...

I am getting about 12.5 average in town/highway. Which I think is fantastic for what I have. My old Nav did basically the same and it wasn't near the truck as my H2. Of course I live out here in the flats, you can see for miles, so it makes the mpg a little better.

Ok guys just got back from San Francisco and I have to report... The worst mileage I got was at the 580fwy 9.8mpg ( doing 80mph in the up hills and down hills). While the best was 13.7mpg around the flat parts of the 5fwy past ButtonWillow ( that was doing 85mph)... But I did get about 12.7mpg on the 101 south ( thats hold 80mph all the way down), and the lowest was 12.4mpg ... So When we got the rig she was registering 10.9mpg and now since the programmer and the oil change we've done better... heres a pic of the DIC...
