Not sure exactly what is wrong... traction I'm gonna say is probbaly #1, the bigger the rim, the worse off you are. they are heavier (more weight to get moving) and the lack of sidewall is killing you. The dyno #'s now from when you pulled it in february sound about right.. how are you shifting the car? If you're taking your foot of the floor between shifts, that's alot of the problem there.. you have to drive a stick car like you want to kill/break it to get it to run the #... that I know first hand, and is the reason I'm taking it out of my car.
The launch off idle does hurt, but not enough to have the results you are having. My carlast year made 403 to the tires thru a 12 bolt and steel driveshaft, and the first pass every time I take it to the track, I usually launched the car off idle like from a stop light, and the 60 foot would be alot worse, and the mph would usually be about 3 mph off, launching off idle the best I ever did was a 12.79@111.84, 60 foot usually aorund 1.95 to 2.05 and the best ever running the car as hard as I could, was a 12.22@114.7, best 60 foot was a 1.72. I'm gonna say either you aren't hammering the car hard enough between shifts, the air up there in rain country is alot bigger factor then I think (new england summer humidity and heat don't help track times much either) or there's somethign totally differnent going on.
I'd advise you to find one of your friends tha can drive good to try taking the car down the track, see if that makes any differnence at all.. just to eliminate that as a possibility.
hope you get it figured out.

I never really ran on street tires, other then when I only had a lid and catback, and at that power level I don't think they were spinning... all my runs were made on 26x11.5x15 et streets, so I never had the down track tire slip issue.. you very well could be having that.

Good choice in tires....I ran mine at 15-17 psi cold (I don't like to go to low with radials)...They like a good burn out and let em rip!
