2009 yamaha nytro Mtx. Supercharged 5-7 lbs boost. That is what i'm presently running with a gems fuel controller. Everything seems to run fine with the occasional intermittent hard start when cold or warmed up. I suspect the fuel controller is causing this. I've been looking for a replacement controller but it seems there is nothing available that you can hook a boost hose up to? I don't understand this. Is there anyone still making this item?
