Towing camper home from myrtle beach yesterday 650 mile day ran strong till last 100 miles made pit stop started truck idle came up to 1000rpm's then back down not normal but air was in and it's usually not. Pulled out got rolling felt sluggish egt gauge was 1500* and only 12# of boost. I have my original quadzilla tuner on it set where it's been forever. Turned it off to ck no difference. Drove home by reading egt gauge trying to keep it under 1300* it sounded like ac blew harder on a pull before problem think I may have a boost leak. Pulled p0299 code this morning. 😡

 

Sounds like a boost leak of some sort.
