Well, regardless of temporary or not, I'd say go ahead and have the ECU chipped/tuned. But with a walbro, larger injectors, and an AFPR, you could probably get away with pulling fuel out using a piggyback controller. Like I said, though, I'd say go with a real tune, ether way. Just remember, there ARE other options besides Hondata, a lot of which are less expensive and just as functional.
