What a Difference a day makes!!

OK, just so you guys know, I never claimed to be smart, just good looking

So I decided to switch programs on the PHP FICM tuner and noticed that i had loaded the 03-04 Econ and not the 05-07 Tune that is correct for my truck. Opps.

So I pulled the injector relay and loaded the +40 for 05-07 and went on my 13 mile test circuit this morning. Stock tune I got 14 MPG at 70 MPH. With the PHP +40 I got 17.2 MPG, a 3.2MPG gain.

I will fill out the complete table and test for PCM corrections factors and let you guys know how it comes out, but for now I am impressed.

Dang! 3.2mpg is a lot! My truck is already getting 18-19mpg highway, if I could get it over 20 that would be awesome. I've never had a vehicle that got 20mpg in my life lol

LOL, what part of "test for PCM correction factor" confused you?

Sounds good, I like how everyone automatically says lie o meter. Mine is pretty accurate somehow and I know I can't be the only one.

Well the most important thing to do is to make sure you and the dash gauge are measuring the same thing. That is why I mentioned checking for PCM correction factor. The only way to calibrate your gauge is to fill it up, reset the PCM gauge and then after some period of time re-fill the tank and do the hand calc.
If you have not re-set the gauge then you will be sampling the same time data and you can see how close your PCM is.

To just say calculated 17.3 by hand but the dash showed 207 means nothing unless your are sampling exactly the same interval.

LOL, but yeah dude look how far from stock you are! I hand calced mine and it was .5 mpg off. So for a stock truck it is more then close enough but when you add all those goodies it may get confused

But after I run my numbers I will re-calc with the tune loaded to make sure I am close to apples to oranges

I bet with all your mods that truck is rightous!
