Why do you need to remove the governor? When are you ever going to take the car that fast? Honestly with your setup the simplest thing to do would be to ditch your MAP bypass and FMU, get 450 cc/min injectors and set the V-AFC to -40% trim across the board until you can have it tuned on a dyno.

Honda motors are reasonably forgiving of loose tuning (i.e. they'll run without blowing up but still can benefit from being dialed in, which is why all of this MAP bypass + FMU stuff works in the first place) and the ECUs--even the OBD-II ones--work on a simple speed-density principle which is simple enough to not get all out of whack when used with piggyback fuel controllers.
