best 1/4 mile was 16.5 sec at 85mph. that was 93P with settings same as above.
i have 2008 SCrew. mods are Gryphon Programmer and K&N CAI. I also have 87 octane in the tank now. its 75% full, so i have to burn this tank and retest the 93P settings again. i am running canned tunes. i will get custom tunes as my mods change. i am looking into exhaust (headers and cat-back), elec. fans, and underdrive pullies. that should really let the engine breathe.

I would go back to your custom tune and take the WOT fuel down to about 1.4, anything over 1.5 is just wasting gas most of the time. I have mine set to 1.35 for the WOT fuel but since you have a CAI I'd go a little higher(try playing with 1.4-1.5).
Do you have the 5.4 and 4wd? You have a little bit heavier cab but even I run 16.1 every time on the 1/4 with highway (3.55) gears and plenty of weight for the brush guard and tool box type of stuff. I also have the 4.6L under the hood.
