What kind of setup are you planning on mating the injector/sprayer with? I think the hobbs is a better way to go personally.

ill be going with just the ic sprayer for now, on a smallish fmic. i was figuring on running a n.o. hobbs set for like 5psi to trigger a relay and turn on the pump.

Im not sure whats a hobbs switch is but I know there is something out there that will work off your maf voltage. more voltage=mroe air=more spray.

I have used hobbs switches with good results, you can get them for any pressure and they usually can be adjusted like +/- 2 psi
