So I just got my car dynoed yesterday (it's still going to the shop it's being built at, and the tq number for me seems pretty low. 
 
I've seen most setups with this turbo put out around the same # hp/tq numbers 
 
Mods:
sr20det with wiseco pistons/eagle rods
Tomei solid lifter kit with 256 cams
Gt28/71r at 12psi
CR racing top mount T25 manifold (modified by TF Works)
Freddy intake (came with the motor)
id1000 injectors 
AEM 320 pump
AEM infinity ecu
Custom intercooler
Stock SR20 tranny with a 3.9 clsd diff
 
If you need more added to the list let me know. I'm thinking it could be a product of the cam profile, but maybe not. I will be going with flex fuel down the line hence teh large injectors and pump. I just want to be able to test out the car and "break it in" without breaking the tranny or anything first, so this is a conservative tune. 
 
If this is normal for the amount of boost, then I'm just an idiot. Maybe I should have had it turned up some more.

Something is off on that dyno sheet. The torque and Hp dont cross at 5252. It mathematically has to cross there so I'm not sure what is wrong with the dyno chart or the dyno.

It will be getting another dyno, but not until spring. That actually is a good point that I didn't even realize.

The torque number seems low. I will be heading to the dyno soon with a similar size turbo aND similar engine setup. I'm I'm the process of doing the headgasket. It LikEly won't happen until the new year.
