It uses the TPS (throttle position sensor) to help it gauge how much fuel the truck is using.
At 50% TPS on stock tuning your PW is Xms @ XXXX ICP.
With a tune, your PW will be wider, and your ICP will possibly be higher as well. Resulting in more fuel injected at the same 50% TPS.
You however, are now using less actual throttle travel to drive around, since you have more power availible. So, the lie-o-meter starts living up to it's name.
Make sense?
The reason your lie-o-meter told you that you were gettin worse milage with PHP tunes than you were with the sniper tuning, is probably because Bill has one of the nicest pedals to daily drive that you can ask for. So, the TPS isn't lying to the trip computer quite so much.
I bet your throttle was more touchy with sniper tuning than it is with the PHP, right?
There was a huge difference on my lie-o-meter when I switched from DP tuning (super touchy pedal), to PHP tunes (almost stock pedal).
