Nice work. Those are SICK drag times! That is as fast as my pro-tuned WRX STi in the 1/4, and I would never guess that truck could move that fast.
Sleeper is an UNDERstatement. More like a "passed-outer."
One tip, I'm not sure if you've tried - On a pro tee, gas it the second you see the tee move. On a "novice" tee, (two yellows then a green), gas it right on the second yellow.
I was told this by one of the fastest drivers in my area, and I can't understand why, but it cut my 60' times dramatically. It obviously reduced my R/T significantly, as well, but the 60' times went from 1.75+ to ~ 1.25, even a 1.19 in my STi. I only red-lighted one time in ten in the STi, and otherwise, my R/Ts were .15 = .2 all night, vs. my previous .9+ R/Ts.
It sounds like you have the truck dialed-in quite nicely. A few more trips to the track and a little attention to the veterans, and you will be in the mid/low 12s all day long. Insane in a truck that size.
