Ok So I want to know if it's true that I need to run a resisitor box if I want to run the RC 720cc injectors, and are they custom injectors for honda motors? This is what I'm hearing from a shop. But I have run 440s and already have the harness and they worked fine. So can someone let me know wtf is going on? More than one reply would help so I can see what's up. Thanks for your help and time
