Gas Mileage after Programmer

[RippSpeed]

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...
