    2mph sounds about right. What RPMS were you at? Try to get right below the limiter before doing anything else. You could do a "mild" Les Cooke reflash and get rid of the boost limiter and raise the RPM limit to 7,300 (stock internals should be good to 7,300). Should be good for another 2mph.

    My ski's gps indicates 0.5 to 1.5 mph faster than my hand held Garmin. I've seen it read 76 mph several times but was only going 74 to 74.5. The real question is why would BRP bias the dang gps like this??

    You should also note I'm running a RS International ECU not the Riva bypass module.
