Lended a hand as tuning/tech support guy at a Supra track rental here at MIR. Managed to get a few passes in with the SS. Don't have the DA (sorry Tony ;) ). Temps were in the mid 70's with a bit of wind coming in at the side. This was the first run with the Yank TT 2600 converter. I went with the 2600 because I still need my towing capacity (for my "real" racecar). The converter install sucked (worse than I anticipated) but I'm happy with it. Maybe I'll get around to doing a write up.
On that topic: Whatever clown @ GM built the truck around the Y-pipe should be beaten with a length of -8 SS braided line.
Now with that out of the way :), driveability is great. Not too loose for putting around town. I can stall it to 2800 on the foot brake. So here we go again:
Last time out was:
R/T - .886
60' - 2.136
1/8 - 9.283@77.34
1/4 - 14.377@96.16
Today I ran a best of 14.07@97. Sixty foot was a 2.002. I had four other passes within a tenth ET wise, sixty foots were within five THOUSANDTHS (.005). I should go bracket racing...
I don't have the slip in front of me, I'll dig it out for the specifics later. I have a feeling torque management is really holding the truck back at this point. I experimented with different launch techniques, flashing it, brake stalling it....it didn't seem to matter. If all goes to plan, I should have Vector's tune in this Saturday.
I made a couple other changes which would probably show more of a benefit @ an evening test and tune. I pulled the passenger headlight out and took the zip wheel to some of the plastic headlight "bucket" (where the headlight sits at). This opened up airflow to the filter (you can actually see it now) and still keeps the OEM headlight clips. Airbox is undisturbed other than the front facing opening enlarged a tad. The headlight was pulled out and the grille was popped back into place for the runs this afternoon.
"Mods" (IE: other than OEM parts..lol) are:
K&N "drop in" Filter
Yank 2600 stall (Ok, that's a mod!)
Pulled headlight
TR55 plugs gapped @ .035
Tires @ 35psi, no spin

I looked up some weather data. The nearest station is 10 miles away, so take it for what it's worth.
Temp: 72
Humidity: 30%
Baro: 30.02
Wind: 6mph, although the flags were waving pretty good.
Track Elevation: 80'
