I'm a bit disappointed, but it's very obvious why. MY TRANS SUCKS!
14.3 @ 100.x (twice) tonight at Firebird in Phoenix AZ.
0-20mph with the stock stall is pig-slow. Brake torque to get the boost up only gets me about 2psi, then I have to launch 5700lbs. At about 25mph the turbo SLAMS me back in the seat. Which is great until the 1-2 shift. It starts to shift at about 40mph or so and doesn't finish shifting until I'm at about 60mph. It's obviously all wasted power not getting to the ground. 2-3 shift is just as bad.
The fix????? New built Trans and a bigger Stall. Even on our slow track here that should yield me a 13.5 with NO problem. (Firebird is notoriously about .3-.4 slower than most tracks, I know, excuses excuses!!)
As soon as my trans is fully fried, I'll go back for more times!
The good news is that I beat an '00-ish GT and an '03-ish GT. And a Maxima, well, duh! I lost to a Heads/Cam/Auto '03 C5. Not horribly, but he took me out of the hole good!
I was suprised my G-Tech times were .5 quicker than the actual track. I've heard they're .1 to .2 off at the most. Seems odd!

You're doin good man. 
Without a stall you won't be able to launch with any real amount of boost. You'll need about 6psi+ to get off the line hard. If I launch under 6psi I lag to high hell and my 60's goes to ****.
I also had trouble with the shifting problem. It was fine at first but at 14psi it would bang off the limiter for awhile then drop into 3rd.
I bet your MPH goes up to about 104mph or so with the trans shifting right. If it's doing it as bad as you say then the MPH is really hurting. I also bet your 60' drops like a rock if you can get it to stall up and launch on 6psi.

Good numbers Your mph is up there good enough for 13's.
Man I know your trans is on its way out but I think a shift kit would do wonders.
Probably too late now though.
When I first installed the turbo mine took forever to shift out, so I didn't beat on it, I promptly installed a shift kit and stall and its doing great so far.
