Band aid fix eh, that would be called an FMU. SAFC, VAFC etc have no way to increase or decrease the pressure that the injectors spray the fuel. If you've got a turbocharged engine and you're using a safc or vafc you've got no clue on what you're doing! Neither of those controllers have any ability to change your ignition maps. This regulator with an apexi is a much more efficient way of getting the job done my friend!
On a side note, this site is ok but offers not near the info superhonda or honda tech offers. Exactly why I don't post here often!
