Car doesn't want to rev!

[Pimpin Dsmstyle]

Problem - Car idles on it's own and will rev normal until only about 2k RPMS. It is extremely hesitant past that. The stock boost gage is reading 14psi and the car is on jack stands. The after market boost gage reads no boost. I know the stock gage is POS but I'm guessing that it's showing a problem since it should not pass zero in neutral. I think it could be the TPS.

History with the car - We rebuilt the bottom end of the motor. It's a 91 TSI awd turbo talon. It has a MBC, volt meter, "a/f gage", boost gage, 2.5 inch exhaust. The car is mainly stock. The timing belt is correct, but the ECU timing isn't set. Regardless to if the cas is inverted or anywhere it can possibly go, the same problem exists. I know the timing needs to be set but I've never done it before and I don't have access to a timing light / alligator clip at this time. I've swapped both the CAS and coil pack off a perfectly working dsm and the problem didn't get any better.
