Hi,
We have codes for several different issues. For example, the air intake temp sensor, mass air flow sensor, throttle actuator, and so on. The one that sticks out to me is P0449 which indicates a large EVAP leak related to the vent solenoid control circuit. If we have a large leak, it could be setting the other codes.
Another concern is the P0049. It shouldn't exist on this vehicle. It is related to an issue with either a turbo or supercharger charger which isn't listed for this vehicle.
By chance, do you have a live data scan tool? If you do, could you let me know the short-term fuel trims?
Also, here is a link that explains how to check for vacuum leaks. See if any are present.

The P0449 indicates a large lean in the EVAP system, specifically, the canister purge valve. This component is located above the fuel tank. See pic 1.
Because accessing the components for inspection is a nightmare, what I recommend is to have the EVAP system smoke tested. Basically, smoke is injected into the system at a very low pressure. If there is a leak, the smoke will come out at that point.
Because this is a large leak, inspect the fuel cap, filler tube, or anything you can see around the fuel tank.
Let me know.
Joe
