Wastegate problem?

Hi everyone I recently started having what I would consider some trouble with my truck.When pulling my boat up hill I noticed it seemed to be struggling more than usual and as i climbed the hill it seemed like it was taking a little longer to shift than normal and once it finally did shift the turbo pressure blew off and made more of a fluttering sound than usual and it seemed to lose boost. so me and a buddy of mine that is going to school for diesel mechanics looked everything over and noticed a possible leak where the hose goes to the intercooler so we tightened the clamps and pulled the boat for a test.It seemed to be a little better but still not quiet right! yet again on the same hill it seemed as if it was struggling to hold boost pressure! keep in mind that it seemed to make a normal amount of boost 17-20 psi but once the truck shifted it didn't want to gain boost again until you let off the throttle and get back in it. so we are thinking the wastegate is going bad? Thanks!

Fuel pressure. Replace your fuel pressure regulator.

Nonconformist. Functionality over bling.

My three rules for 7.3l troubleshooting: 1) Replace CPS and keep a spare. 2) Replace FPR and know your fuel pressure. 3) Hook it to a scanner and check for codes.
