6.4L IM UNEDUCATED Help save my truck please 😂

Even with a relatively light load my power is reduced after around 20 miles going 70-75mph. If I really stomp the pedal it will downshift but my turbo psi stays at 19psi. My EGT’s are relatively normal 775-850 I don’t think that’s the problem. Watching my engine load percentage, when I’m not in ‘limp mode’ my load will be around 35%, I know I’ve been limited when my load jumps to 80-90% and if I press the pedal even slightly it’s at a constant 100%, acceleration is not possible. Fuel filters are replaced, oil and filter just changed, I haven’t cleaned my air filter in a while but I doubt that could have anything to do with it. I have an H&S tune set on 120hp, it’s not on ‘easy’ or ‘wild’ it’s the one in between. EGR delete, all that. AGAIN, NO CODES AT ALL. If anyone has any idea what this could be please let me know I’m trying to keep this truck working. Ask me some questions
