Wont rev past 3k

[cman3000]

Hey, so i just got matts 91 awd tsi, 5 speed, and got the tranny fixed on it. tried driving the car home, but it would get to 2k, start sputtering, and wouldnt get past 3. I could even downshift and the car would go to 4k, but there would be no throttle response at all. Occasionally i will start the car up and it will rev all the way(still sputtering a little), but it doesnt last long. Thought it was the TPS, but i took that off today and it tested fine. Could it possibly be the fuel pump? Im not hearing it whine when i turn the key. Mabey something was not hooked back up when the tranny was fixed? Any opinions would help greatly.
