    Throttle response 05' RXP vs 12' RXPX?

    I picked up my 2012 RXPX a month ago.. just had second ride.. quick question for you guys. My 05' RXP will kill my 12' RXPX out of the whole.. not for cavitation.. both skis hook up great..but the throttle mapping.. the older ski is like a banshee.. and the new ski is slow to ramp up .. even in SPORT mode.. is this a function of the throttle by wire? I have the Riva stage 1 on the new ski, and the old RXP beats it out of the hole and both sit at 68 flat out.. what gives?

    sounds like you're stuck in the default mode, when you floor the ski does it give full boost, what does rpm do as soon as you floor it? the new rxp comes out of the hole very well.

    Yes.. the boost gauge maxes out.. and its VERY responsive after you get going.. but uber slow up to about 20

    Something's going on...... Go over all the simple things first. Spark plugs, engine compression etc. Double check the prop & wear ring as well. Is this a new issue? Or have you always had issues with the 260? There's no way a healthy 260 in sport mode will get beat up by a stock 05' 215.

    The stock 12-13 skis feel very lethargic until you tune them.

    Drive by wire will always have a slower throttle response then cable. But your stock fuel mapping is most likely playing a large part in this. Even tho these ski's are performance ski's they still have a rubber band around the balls from the factory.

    Something isn't right. 2005 RXP shouldn't take you out of the hole or at any speed with out some mods done.

    On my stock RXPX 20 MPH comes at basically a blink of an eye.

    Do have a tune on your ski? If so I'd call them and tell them something isn't right. If there is no tune do you notice a huge difference in throttle response from Sport and Normal mode? Because it should be very apparent.
