    Ultra 250x low rpm

    Hey everyone I am just wondering what everyone is running on rpms on these skis. Mine only has 17hours on it and I have never been able to get it over 7000rpms normally its around 6600-6800rpms and I am running about 7-8lbs of boost. Let me know if you guys think. THANKS

    Start with simple stuff like plug, hoses, fuel quality, air intake sucking against the hull ect....

    hey I went thru all the clamps I could tighten and they are good. I pulled the plugs and they look good. What do you guys recommend for plugs? Also I will be doing the BOV block off. Any other tips would surely help thanks

    The ski is stock, I live in north eastern Utah. My elevation is between 5000-6500ft. It has been this way since it was new. I will have to get a tool for the belt, It is getting full throttle. and how do I check the intercooler for oil.
