Losing boost
Has anyone had issues of only getting about 40% boost the valve on the driver side muffler won’t open up and I believe that’s causing it trying to see if anyone else has had this issue

Very common. When the exhaust valve actuator fails, it throws a code to the CPC to cut boost. You'll need to replace the faulty exhaust valve actuator or tune your CPC to deal with the code.
