It spools to 8psi by about 2800 and then keeps going to 12 psi at 4k and stops climbing there.

those little turbos are spooling hard on you...
Some options off the top of my head, in the order preferred:
1) Get more fuel and make more power =)
2) See if you can reduce the tension on the wastegate springs
3) See if the wastegate flapper is large enough to port the wastegate out for more flow
4) Make your exhaust more restrictive - what exhaust are you running from the turbo back?
Aside from that, you can also consider the far more expensive options of plumbing in external wastegates or upgrading to much larger turbos =)
I'm sure someone smarter than me will chime in with more options as well =)
I wonder if your tuner can pull some timing to keep it from spooling so much on you? That is pure speculation as I do not really understand the technical aspects of tuning in this scenario.
