I have attached a list of N55 codes and corresponding info to help you troubleshoot.
I battle codes on a weekly basis, always chasing an issue with this car...

Do you have an aftermarket intake, BMS or Injen?
I had those tmap errors and the only way to resolve was to run a jumper from the tmap ground and ground it on the closest ground point in the engine bay. I think the grounds in the ECU got fried, by so many Jb4 handlings and use... was running into limp mode quite often with those tmap faults. It is documented on other forums of similar issues with Jb4 use and tmap issues.
I know its not the tmap itself since i have the stock one and use the 3.5 bar for higher than 20+psi with the larger Pure turbo setup
