best 0-60 was 9.12s. that was with 87T and WOT set to 5000rpm, WOT Fuel set to 1.8%, and Shift set to 25.

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.

Was messing with mine the other day since I am awaiting custom tune for my Gryphon, hopefully I will see the difference.

5.4L 2wd
I got: K&N CAI, Borla Exhaust, and the Gryphon set to tow tune

1/4 time: 15.68 with 1.2 reaction time(yea horrible reaction)
That was just leaving it in drive and taking the O/D off... so I haven't even tried sport shifting it yet.
Hoping to run low 15s when I bring it to the track... 15.2 to be exact.

I dont think shifting from 1-2-3 will improve your time any because the manual 1st has a throttle postion distortion so the pedal on the floor will not have as much power as the regular pedal on the floor. I think the manual shift also takes a hair longer. I've found that once you know where your WOT shift points are by speed/sound you wait for it to get close then let off for the shift then get back on it. Is this on 87,91 or 93?

That is one thing I did not mention... it is 87, SHELL!
That is the only gas I put in my baby.

Yeah, I've been running shell lately because they are only 1 cent more than the cheapest gas station for 30 miles(still $2.75 though ). I get better power and about 15% increase in mileage compared to the others. Next best stuff is from an HEB, I also get good mileage on that even though the power isn't quite as good.

$2.90 for 87oct straight gas here.
