    I ran a pitched 15/20 with that set up.
    first thing we need to know is your rpms as you may be on the limiter.
    stock ecu?
    i ran that set up with out FPR, but i monitored afr. It is always a good thing to monotor.

    I second what Water4Fire says for sure. We need to know your RPM's How many hours on the machine?
    Fresh or salt water use?
    Some benefit from a RRFPR, some don't. Mine does, so you should first monitor it, see where your at.
    As this is an 06, should he look at the valves? Are they ok or are they the ones that could break?

    i did not inspect what valves are in my engine , but i will check before season open , because i know about this problem.


    my ecu is stock , water is fresh , hours on dash 108h


    i repich impeller if i good remember my rmp is about 8140~ or 8180 ~ this setup i test only one time because season closed...

    water4fire whats is your top speed?

    Your 14/19 is not enough and your running the engine on the rev limiter at 8180. The correct impeller for you is a 15/20R
    In your cooler riding area in Lithuania you absolutely need the RRFPR.
    Your speedometer will not read more than 70 mph. You need a hand held GPS to gauge your true speed.

    I ran a similar setup last year with a 15/21 on my 07 and was seeing 75 on gps at 8160, are you just going off the dash speedometer? It will stop reading over 70 and isn't accurate anyway.

    In that cool water, yes! your engine is running lean. You need the rising rate fuel pressure regulator. In your cooler climate you may be able to use the 15/22. If RPM is too low simply depitch the trailing edge 2 mm. It's very easy to do. Instructions here http://greenhulk.net/forums/showthread.php?t=2614

    Correct! The RIVA rising rate fuel pressure regulator I linked you to comes pre set, but it's good to always check it once installed on the ski.
