6.4 single H&S. No boost

Drove the truck home on Sunday and truck run great. Went out on Monday and started it up and on the way to town truck was making zero boost. Still seems to be running fine, other then no powe and making zero boost. Checked cold and hot side piping clamps, which are all right and everything is all hooked up.

Any ideas where to start looking tonight when I get done working. Throws no codes.

any exhaust leaks? Sensors are all hooked up correctly?

If it's truly producing zero boost then you either have a massive boost or exhaust leak.

No boost or exhaust leaks, all piping is connected and boots are good. Will look in to more tonight when I get home. Thanks for the responses.

Have you inspected the turbocharger to make sure it spins free and true and that there's no wheel damage?

Kinda what I was thinking. Or is the manifold pressure plugged in but not screwed in.

Sounds like map sensor is not reading
