if i have it mapped with a setup like this can i just fit a ebc at a later date or does it need to be set up on the rollers again?
That is just a fancy mechanical bleed valve.
Depends how much it changes your boost control by. Some EBC's can allow it to spool earlier and hold boost better at the top end. So ideally yes the car would need checked and possibly remapped under real conditions on the road. But also depends how it was mapped.
If whatever rollers you use can load the car up exactly the same as on the road, then that is another option.
