P0299 & p0227 Anyone had any issues with these two codes? It has 31,000 miles. It says turbo underboost and barometric pressure sensor. I’ve replaced the air intake sensor in the neck of the air intake and the turbo solenoid sensor on the front of the turbo. The car immediately goes into reduced power mode. The car hit a deer and we replaced the radiator, grill shutter and cooling fan but all work correctly and there doesn’t seem to be any loose intercooler pipes or air intake pipes. Any help would be greatly appreciated!!

Maybe a hole in the inter-cooler or in the pipes?
