For 2-3lbs of boost, you'd be fine with just a 12:1 FMU. If you wanted a way to tune your fuel curve(since you'll run very rich otherwise), you can run a piggyback fuel controller like an AFC or SFC. For up to about 8lbs of boost, the FMU setup should still be fine, but you'll want to add an inline fuel pupmp to provide the higher fuel pressure you'll be needing. If you go above 8lbs of boost or so, I would ditch the FMU setup and look into larger injectors, which you could use with an AFC or a standalone unit. If you go with larger injectors, a high-volume in-tank pump would be a good idea. Of course, a good standalone unit(Hondata, EMS, etc) and larger injectors would be the best tuning option, but for minimal boost, the FMU should be fine.
