    HELP!!.. Shinny New GTR in my garage! Now what??

    Hello fella's,

    Finally bit the bullet and bought a new SeaDoo GTR 215 after owning Yamahas all my life (since 1986sh adn still have 2 Yamis!!!) so I'm pretty psyched about it... so now I need your help...

    what are the "best" mods out there that I can make to this thing?? (Yeah I would like to make it a RXP260 but my wallet would only go so far )...

    Also- what should I "watch for" on this particular unit/brand??


    So what would be the first thing you'd do?? let's hear it-

    thanks everyone!

    Vtech to reflash your ECU! That will remove all seadoo's 3 limiters! GPS, Boost, RPM!

    You need modified or change your intake grate, bigger charger, reflash and high efficiency intercooler.

    ET means Engine Tech. 127 and 137 are the diameters (in mm) of the supercharger impellers.
