Looking on RST Mania and found a link to do with fuelling mods with the pressure actuator on the side of the metering head. I am wanting to get this adjusted due to me pinking at 17PSi. Is this mod worth doing. I have been looking into making up a fith injector kit with an adjustable pressure activated switch which I've got off ebay. I wanted to wire it up so it turns on the cold start valve at a certain PSI. Has anyone done this mod? Obviously I'd need to get it set up properly on the rollers once its been done.
