well i thought i should update this, took the car for a ride tonight, left on the pulley that came with it (3.6 inch) and it hit 8 psi a few times and once 9 psi, at 7000rpm. id like to be at 6-7 for now till i can get the tuning sorted out, what do you guys recomend.
Thanks in advance
Heres some pics of the finished product

thanks guys, the new ecu should be here tommorow and the wideband with it.
Funny thing, i forgot that i had set my redline to 6500 rpm for the test drive (7000 is normal) and i hit 9 psi max at 6500 rpm, which was too much as it is, i can only assume its gonna get worse in the last 500rpm so i went ahead and ordered a billet 4.0 inch pulley hoping that will get me down to 6-7 psi at 7000rpm where i want to be.
The motor can take more boost but right now im limited by my injectors to less than 450whp and i dont want to get close enough to risk it. Dyno will be on friday ill post up my results. Thanks again.

well guys thought i would update this..
The 4.0 inch pulley gave me exactly 6psi at 7200 rpm and the car picked up nice power, i wasnt expecting it to pick up power everywhere north of 3000rpm but id did. I had a few issues but got them worked out, here is the dyno sheet Thanks for the help again.

Nice clean 240. While I don't like them in general, yours is awesome 
.
You should have bought bigger injectors instead of a different pulley, though! Now you still have to buy bigger injectors when you want more power (you know you will) and then you will just go right back to the original pulley. Regardless, I hope we were at least a little helpful!
