So build question im running a 6.0 iron block 408 stroker in my 2005 gto and curious if the stock ecu after being tuned will be able to run, drive, and race or if i would have to go stand alone

It should be fine. There is a 63lb/hr injector size limit you can enter on those ECMs but there are even ways around that. That injector size limit should be plenty for a heads/cam 408 unless you plan on running E85 or forced induction.

Plan on going single turbo in the future but not anything soon

The computer is fine for what you want to do. I have HPTuners and I keep a tune for the street and one for the track but it is only a transmission change. The engine tune stays the same, I just like to give it a little softer shift for daily driving. I'm running 94# injectors and corn juice so it will handle just about whatever you want unless you go crazy big.
