I just fixed a truck with similar symptoms. The two pucks that seal the exhaust port in the wastegate had broken off the lever arm. Changed the turbine housing and it was back to normal.

Well that covers the spool part. I'd suspect something more like governor springs not tight enough or the rack not hitting full throw. Any fuel plate in there? Sure the AFC is traveling all the way? I'd pull the foot and see if it picks up boost.
If it was a boost leak usually it gets hot and smokey. What's your EGTs full pedal? Any smoke?

Based on boost numbers from some of your other post, it sounds like you still have wastegate issues or adjusting to do.
