Wondering if I should flash back to stock tune with the GDE PG3 before loading stock tune to HD's PG3 or can I use the EPA compliant tune as the stock tune for the HD?

Yep, put that stock tune back before copying it to the device provided by HD.
Why the switch from GDE to HD?

EGR. I love the tune, but don't want the soot in the engine.
