Power loss and stumbling at high rpms

1993 900T manual, 2.5" downpipe back
Having issues with the car bogging out at the top end. I can usually get to redline in first gear and then second gear about 4k i cant get any more power and the car is starved for power, stumbles and backfires a bit.
Aside from this, the car runs smooth. One thing to note is that the turbo isn't putting out as much power as it sould. My gauge reads 3psi max WOT.
What could this be? TPS? Turbo?
Vacuum leaks are sorted AFAIK
