no power

Alright guys I'm super confused on this one. Just got the motor rebuild and it feels like it has no power. When i give it more gas the boost gauge goes up but the car doesn't go any faster. When I give it a little gas it goes but not fast. I have tried a different ecu different injectors. I've checked for boost leaks there's none. I was just wondering what you guys think the problem is. The check engine is not on either.

check timing belt position, cam/crank sensor, tps set right, throttle cable on correctly, compression, mass sensor operating correctly, fuel pressure...
I'm just throwing stuff out there of things to check if you haven't. what is the car doing when you accelerate? sputtering or just accelerating slowly? (when you give it a lot of gas that is)

I know there is other people here that can chime in w/ better information but seems like you should check a few things.
make sure there is no debris in your mass air flow sensor and start double checking everything like your tps position, timing, fuel delivery, be absolutely positive no boost leaks... stupid but make sure the plugs are gapped correctly and the wires are on correctly and all electrical plugs are plugged in all the way and vacuum lines are correctly routed. seems like a logger is going to help you in this situation so if you can get one i would recommend it. If you already swapped in known good ecu and injectors you can put that to the side and start on this other stuff.
hopefully some of this helps. if it was running well before i would assume it has to be a simple mistake made on reassembly.

Without any kind of datalogging capabilities it is going to be hard to diagnose and correct the problem you are having.
 

Check your timing belt tensioner, sounds like you may of jumped your timing. Just check to make sure your car is in time. Because that would definatley do it.
