Yeah anything over 35psi is out of that turbo's efficiency range and your just now blowing hot air. Thus why it feels like your losing power. Turning the box down you aren't flow as much fuel so I'm sure your pressure is down lower. So with that said things to look for are that the wastegate is hooked up. If it has a boost elbow on it try adjusting that and see if you can get that pressure down to 35psi or a little lower and if that doesn't worked I'd say it has either been plugged off or possibly it's frozen shut. Sounds more like it's just not opening up.
