To answer your original question, yes it will still need recoding and testing with the immobilizer to make sure they are pairing correctly, otherwise the car will not run.
That said, if the exact reason that they feel you need a DME is "the DME is not sending a signal to the MAF", you have a bigger problem: They do not know what they are doing. On your car, the MAF sends signals to the DME, not the other way around. The DME takes information from the MAF and other sensors to make corrections in the fuel mixture, etc..
I'd suggest getting a qualified second opinion from a shop that works specifically on Porsche's, and has a Porsche diagnostic system. You cannot correctly diagnose these cars with "global" OBD II scanners, you need the correct system.
