    I did this upgrade last fall, I put a les
    Cooke 8600 stock class ecu on my px..
    I also had to upgrade to Les Cooke retainers...

    Gains... I saw 13lbs of boost and picked up of a few mph..
    I upgraded to et137 on it over the winter but never had a chance to run it, before I upgraded sc again...

    Im assuming your just looking to up leave ski stock but up the rev limiter..


    Initial gain with just a raised rpm limit (8400rpm) is going to be a few miles an hour..

    Les can reflash the ecu to match the SC components on the ski so need to add other fuel controlling devices (unless you already have it)

    I know Les does reflash so you can still run the oem valve train and if I'm not mistaken the rev limiter is set at 8450
