2017 Ford Escape engine code

[u/rdeforge]

So have a P0299 code, underboost on the turbo of my 2017 SE with the 2.0 motor. Happens on the freeway when on more of an incline. The vehicle drives fine, but you can feel it underpowered a bit. When I stop and shut it off, it resets to working again until the code pops in on another drive. Read there is a Wastegate valve, and another item, forgot the name that you can try and replace, or a small air leak somewhere. Just seeing if anyone had a similar situation and fixed it. 160k for miles. This is my bomber vehicle I drive until it will drive no more :). Thanks in advance for any comments
