    Anyone Have Top Speed Numbers with 109HP VTech Tune?

    For those who have flashed their ECU, do you have any accurate GPS top speed numbers?

    Problem with the Spark is the crap scoop grate ... Even with 600 rpm increase it doesn't gain much top speed ...

    it needs a new scoop grate to grab more water as it Max's out at 80 kph ish with stock grate ...

    Has anyone tried removing the grate? On x4's it was always worth .5-1 mph

    Just curious........

    How do they claim 109 HP??? I have been told by several BRP engineers and some with Rotax who say that the motor WILL NOT make more than 100hp without changing anything other than a tune????

    I am not knocking Vtech, just curious what else you all have changed or had to change to get to this 109 number????

    So I Guess a 2 MPH Scoop Grate is going to be "Like Gold" for those of us that have to be Tad faster than the next guy???

    I've always been under the impression that a large scoop means better hook up in chop, but more drag which means less speed.
