Default first start on new turbo setup, running rich

Hi there, i just did the first start on the turbo setup for my project car, i have deka's 80, single walbro 450, speed density and a 76mm turbo. I got a frost tune for the setup and to remove vats.

Problem is that the car is running super rich, and it wont rev past 2.5k-3k , i checked the o2 sensors and they are good with no visible problems as they are new, along with the spark plugs and wires.

I was told by the tuner to set up base fuel pressure at 50 with the vacuum port connected to the reference port on the intake manifold and i have that one connected already.

Any input about how to star troubleshooting this issue is greatly appreciated, thanks !
