Air/fuel ratio C (m) = 14.5-15

What is your MPG, from what I know, -10 LFTF at idle is not supposed to be right (this is what the dealer told me).

Yesterday I disconnect all 4 O2 sensors, and all those value stay the same and no check engine light come on even if I have 4 pendant code when reading fault code. The truck was performing as good as with sensors connected.

overall average is 16.5(corrected), thats with a lot of 70+, offroading, etc but if i drive nicely i can achieve 18+, my commute to work this morning was 19 (18 if i consider the computer is almost 1 mpg off), 68ish and some stop/go traffic.

I can't ask for more, thanks. You have the same weird number as I have, with those number, my dealer said I'll never have great MPG, but you have good MPG. I have another visit to dealer next week to install the new intercooler so I'll show your number.
You have average AF ratio of 14.5 during your trip, so the truck run a bit rich. I got a average of 14 during a hour trip, but the computer never correct it.
