The problem is your turbo. Take it off.

If the MAF is unplugged the car should DIE Immediately, as the ECU will see no air moving into the vehicle. Unless you have some weird MAF emulator on your FL link that Im not to familiar with.

By the fact that you are still getting fuel, I would suspect a leaky injector..... The motor should trot in a almost dying state but still run.

MAF low voltage code is caused by that MAF benig unplugged, I get this code all the time when starting my car with the AC on and using the xede. The car will test the MAF on startup and if it is not getting the correct voltage you will get the code.

Second if the link runs on a map sensor and controls the injector duty , maybe you could have trapped pressure? Or just a bad ECU and or wiring.
