I would say you would need a base map just to be on the safe side.

in theroy the maf sensor will allow the ecu to see the extra air consumed by the 2.1 and fuel extra for it off boost safely.. however if the engine has been rebuilt because it blew then the cause of the failure might still be present (maf fault, injector problem) etc..
Also a lot has been removed and refitted in the engine bay, easy to have a vac hose connected wrong, or something very simple that could cause an issue.

With the cost of the rebuild it is well worth just making sure it is fine and safe to run in.

If you have the self discipline you could run it in STRICTLY off boost as in ZERO boost. That's what I did with mine
then fitted bigger injectors at
remap. Most are not able to do this so a running in map is the safest option.
