    Cool Rotax upgrade Riva Pro Charger 42lbs and Racing ECU . Is this worth doing ?

    Planning on this as my first mod to a 2005 seadoo challenger please advise if it's a good start and what to expect in difference ??? And will this work with just the charger and injectors temporarily ??

    Always check your AF on a new setup. Never assume that everything will work togeather because it did for someone else

    he means your air/fuel ratio. which means that if you are to lean with your mods and you are running the hell out of it = burned up. or to rich which isnt as bad as being to lean

    lean = you need more fuel
    rich = you need less fuel

    Sweet ok so to change the Air fuel ratio possibly need to fit dual regulator right ??
