bone stock all is tight checked all couplings sounds like it just goes into exhaust.just checked fuel pressure it drops off to 30 when it reaches boost maybe the pump?

If it is the stock pump then I would say start there. Does it set any codes?

Plugged exhaust (Cat)???

i've seen this cause many boost related problems.. try disconnecting your exhaust and take a spin in it and see if it's alive again or same result
