    300x loss Of performance?

    Hi

    I have a 300x, totally standard, serviced regularly my main dealer, 28 hours, exhaust gasket checked at 23 hours.

    Went out last weekend and the ski when running wot runs at 67 mph @ 7340 rpm with the boost gauge showing 13 psi.

    Is this normal as I am sure it used to register more boost on the gauge, also I think it used to rev higher?

    Any suggestions, ski is still in warranty so I can take it back to the dealer, your input would be appreciated.

    Cheers

    Check all hoses and clamps make sure there tight. Check your ex filter.check speed with gps. If no scom then 67 is as good as it gets.

    Given it's all stock those numbers look about right.

    You may just be used to the power now

    With a SCOM yes. But stock, once it hits speed it drops down to a level to maintain that "maximum" speed. It's probably ok but as posted above check all you hose clamps to be sure. They do loosen in the first 10-20 hours.
