When we first put on the Vortech, we had completely stock exhaust. We used the stock Vortech pulley. It performed ok, but we were looking for more..
We went with high-flow cats, Greddy Evo2 cat-back, and the 3.12 Vortech pulley, tuned by Tuan @ GRD yesterday. Still using the Split Second box.
Results - 378 rwhp, 320 tq SAE on a Dynapack dyno. This is a 2004 Touring 5AT.
The car pulls amazing (especially in the 27 degree Chicago weather)
Thanks to the GRD crew.

Being Auto you really have an advantage off the line.

Seems that autos dont loose too much thru the drive train

With the stock exhaust and pulley, we had 318 on Sharif's I believe.
Hard to compare different dyno's on different days.

We will!! He's already driven her a lot! I get to drive her tomorrow before she goes in for the valve body.
She's such a biatch!!! I LOVE HER!!!
Nice work..I am glad you found a tuner closer to your home...at least a little bit closer! That is definately a power improvement you can FEEL with those extra mods and boost! 
Is the trans shifting OK?

I'm calling you tomorrow to order up the valve body upgrade. It is going in a local shop on Tuesday to pull it.
