I was wondering why they were so low.

Manual Boost controllers don't effect your TQ like that. Going on just a hunch here, but I think it's your 3 inch exhaust causing the low tQ #'s.

Nice numbers for low boost! I am interested in how all of your NY boys get around the fact that we are pretty well CA standards. I am looking at boosting in the spring but dont want all the hassle of the big man on my back.
Also, I agree with the exhaust. In my mind if you aren't pushing some VERY large number a 3" exhaust is just unnecessary, 2.5" is plenty.

I dont understand how 260 ft-lb torque is a low number? I spin my tires enough as it is.. not complaining.
The exhaust is perfect for my setup. Even if it wasnt.. I cannot justify spending $500 on a 2.5" exhaust and a few months later spending another $500 on the same thing and taking a huge loss

The 2az commonly produces more TQ than it does HP, or right at the same. Your dyno is SOO far off from every other boosted tC that has come before you. If you search around, you will find just about every dyno you come across, having MORE torque at the wheels than they do HP. That's why we love our Scions so much, and talk **** to Honda boys. Because we have the TQ to back it up. From my knowledge, it is not until like 500+whp Digit numbers will you start seeing the HP numbers creep away from TQ numbers.
Take a look, all of the turbo cars (S/C'er tC's are the exception because they produce a lot less tQ than their hp), you will find everyone producing more tQ than they do HP. Anywhere from 230whp on up to 450whp. All the Turboed tC's have more tQ.
You dynoed 291whp. Your torque should be 300+lbs, not 260. I believe again, this is due to having to large of an exhaust system for that HP level. Now, if you plan on going 400+whp, then don't worry about it. You can benefit from it LATER. But as of right NOW, your exhaust is basically to big for your power.

My wife's car has a greddy kit on it with a 38mm tial set to 8psi, and we can't take it above 5k right now because we're having fuel issues.. But at 5k, it out down 274whp! I'll have to check the dyno sheet to see what the torque was. I'll have her car around 300whp with a new emanage.

What everyone has said about 3" exhausts being too big are completely wrong! A less restrictive exhaust can never be bad for a turbo car. Turbos love bigger exhausts becuase they can flow more freely. Your car is going to produce more power and spool much faster w/ a big exhaust becuase it will take less energy to produce the desired psi.

^^^ NO! the exhaust gases gets out way too fast for the turbo engine to produce ample neck-snapping torque/restriction.
That is bad unless you like driving cars with high end power and low tq. ( also, restriction has something to do with torque.)
