    Rxp x 255 is stage 1 ecu flash

    Hey bought stage 1 flash file and got 8080 rpm on stock file and the same on the tune. Have only tested it one time.

    Wot run today 14C' sea temp 16C' air temp 114kmh mobile phone gps. Stock intake and adonis 15/21 impeller and bigger intercooler.

    What should rpm increase be on a good tune?

    You will not see a speed increase on that ski with just a tune. They only have a rev limiter unlike the newer skis that also have a speed limiter.

    So it's just the acceleration on tune.
    Will a intake flame arrestor delete and a 4" cone filter help with getting higer rpm? Revlimiter is set to 8400rpm.

    No, the tune will not improve your acceleration or top speed or anything as is. You haven't made changes to the engine to give you more power for acceleration or top speed (bigger impeller). For the tune to make it safe to use.

    Unless you replaced the flywheel bolts, I wouldn't go past the stock RPMs. The tune only removes the RPM limiter for your STOCK set up.
    If you make changes to the engine so you can make more power to spin a bigger impeller then the tune can adjust air fuel ratio for the modifications.

    As is, you wasted your money on the tune. The tune is the same as stock, which is the most efficient set up.

    The only way to make use of the tune is to replace the supercharger wheel, intercooler and fuel injectors, air intake, flywheel bolts, AFR gauge, etc. It will also be less reliable.

    What they are trying to say is you're putting the cart before the horse. You need to do several things to take advantage of the factory tune before you go from there. RR
