    and now \for even more question: do i have too do any fuel injectors mods or remaping of any fuel stuff.. i dont have that stuff.. snap on tools yes.. mapers no... lol ..

    i dont know much of what your setup and suggestions, but i can suggest one thing. the first thing you should do is swap out those ceramics for jerry's washers pronto!

    I have never heard of an RR ECU causing a ski to run hot???

    The cooler thermostat is always a good idea as it reduces heat fade, but you aren't going to overheat without it.

    Get the ceramic washers out of your supercharger ASAP! Upgrade to the metal ones and be done with it.
    By the way, the supercharger impeller doesn't have ceramic blades, they are aluminum.

    Also, it sounds like your ski is stock with the exception of the RR ECU? If so then your air fuel ratio is way too rich. You need a minimum of an external intercooler to run that ECU. Its also a good idea to upgrade the valvetrain to handle the higher RPM's this ECU is capable of.
