    Bone stock Yamaha GP1800 goes 79+ mph with only MaptunerX tune

    I figured this accomplishment deserved it's own post

    I just got back from riding my new GP1800 with MaptunerX reflash and it ran 79.2 mph at 8300 RPM

    YES! still bone stock, impeller not tweaked, ride plate not tweaked. Fresh out the Yamaha crate and only a MaptunerX tune. I'm amazed! Can't wait to see what this thing will do once i start adding mods tomorrow

    Here's a video of that 79 mph run





    Stay tuned guys, much better speeds to come once mods are added. You can follow the build progress of this ski right here on this thread

    I think you are forcing me to get a new ski.

    Is the new GP hull that much faster than the FX SVHO ski? Nice results

    apparently so!
    And in comparison, my bone stock FZ SVHO ran 76-77 with a tune only.
