    Welcome to the Hulk!

    This was originally written for 255/260 HP skis, but a lot of it still applies to the new GTR.

    I diddn't see anything in there about a reflash, or socom, or other form of GPS limiter work-around.

    Pretty sure that until you get a re-flash/stand alone (MoTec, Athena(Riva), Les Cooke, V-tech), thats about all you will be able to get out of it.

    'surferd15' has a thread on the build of his GTR, and a decent re-flash seems to be his limitation, if I remember correctly.

    Your ski has limiters built into the ECU. You have a GPS limiter which is set at about 68MPH and a Rev limiter for your RPM's. Not sure what your boost is limited at or how far you can push it on a GTR but I'm almost positive there will be limiter on the boost it produces (it does on the 260 motors).

    All the mods in the world will not get you pass those limits with out doing a ECU flash(V-Tech or R&D) or stand alone ecu like the Athena.

    You need to spend that $600 to $1300 on the ECU and then you'll break 70MPH with your mods and have better pull through the rev range.

    Vetch ecu flash
    4" air intake
    Ride and intake plate upgrades.

    Keep the updates coming. GTR owners need all the mod info they can get.
