    2005 Rxt 215

    Hey guys I need a bit of gel in regards with trying to maximise speed on my ski. Air Intake, prop, intake grate and sponsons have already been done. I was thinking of buying a 15+ pound supercharger but would like to know if anything needs to be done inside engine, I'm a fan of speed and just want to take it to next level with this ski. Any help would be much appreciated thx

    regards , steve

    welcome to the GH

    many, many posts here about upgrades
    I also started moding on a 05 215
    first the 05's have weak valves
    there are a few posts on the disasters with broken valves
    if that does not shake you up
    then your ready for a ecu reflash with larger injectors to go with the bigger charger
    if you don't re-flash your ecu and use the CMD with auto tune for fueling
    you will need a voltage clamp on the map sensor because the 05 ecu map goes to 100% DS around 12psi
    again welcome to the best forum for pwc performance and happy reading
