My car hesitates/sputtering when boosting

[96TurboAWD]

I am not sure if its a boost leak. I have a T-25 with a mbc at 15psi but when I start to boost it feels shakky and the gauge keeps bouncing. I just got a new Cam Angle Sensor and my Balance shaft belt snapped got that replaced and timing belt and so on. It runs fine until it wants to boost. Its at about 2800 where it acts up? What could it be except for a boost leak I can't find?

When you say the boost feels shaky what do you mean? Or is it, the car itself feels shaky or vibrates real bad. You mentioned you have the timing belt recently replaced, might have the oil sprocket out of phase. Explain a little more about the shaking.

my dsm does that when its really cold out, it will hesitate, i guess i cant really explain how it feels, but i think people know what "hesitate" means.. i got boost creep though, boosts up to 20 psi when i punch it in a high gear at like 2000 rpm.. but it goes back down...time for an MBC for me.
