Car as been running excellent! Until I decided to make all the piping uniform after the charge pipe with 2.25" as that is what the factory cross pipe is. I received both codes and had misfires. I put everything back to the way it was today. Car had been sitting with the battery disconnecting and the codes cleared for two weeks. I turned the car on and there was the CEL's again. I had already replaced the MAP sensor and saw that the connection to the N75 wasn't tight so I pushed it in. Car drives fine with no boost under 45mph.

I have searched through various others reporting the same issues without finding and actual solution. What solution is there or what else should I try?

I'm posting all photos taken from the diagnostic scans.

I was able to diagnose the problem. In my case, when I was removing my old MAP sensor one of the three wires to the MAP harness came disconnected inside the harness. I tested this by gently tugging on the wires and one came out easily so I stripped the wire back a half inch and pushed it in. If this happens to you I would also check the wiring under the heat shield to ensure nothing has happened.
