    Gps your speed.

    The dreamometer is not reliable on any manufacturers skis.

    The worst is yamaha. They will say 75+ and your doing 64 gps.

    Yeah my fully modded GPR with all the bells and whistles said 98 mph but of course GPS said 75-76...

    Like these guys on Craigslist saying "stock ski does 75 mph" ...yeah more like 63..

    OP was that a visual top reading on gauge or the memory feature..visual is more accuracy also kept in mind air temps and ESPECIALLY humidity will make a 200-300 rpm difference on these forced induction engines..
