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.

 I guess its cheaper over here because we've got refineries so they dont have to ship it as far.
