    speed problem on my 300x

    hi guys.
    good day!

    Need your assistance on the below.
    I have a 2011 Ultra 300x, but since about 1 year, it start to give me some problem. I can not go over 7,200 rpm, boost aprox. 12
    Speed, no more that 65 mph.

    I have installed all the stage 1, plus impeller the solas 14/21.

    I checked all hoses, line, IC, everything.
    Changed the ride plate to R&D, the exhaust filter. Mean I did everything I guess.

    I hear all kind of recommendation and followed, but nothing changed.

    Last thing, is to change or checked the SCOM, if it’s in good condition
    Is there any way I can checked if same is in good working condition, or I need to buy a new one

    Please to hear your recommendation.

    Thanks.
    Gian

    What SCOM do you have ? Sounds like your ski is still limited and the SCOM may not be hooked up correctly , RPMs are low but you do have a 14/21 so if should be around 7700 to 7850 .. Do you have BOV block off ?

    That's what a was thinging. When I installed it, I noticed the different, but suddently all changed. I have the Riva scom and the BOV block off.

    you sure you don't have a boos leak?

    I've checked everything and not. Do you thing the scom is damaged. Do you know how can I test it, before spending money on new one.
    Also, do you know what is the psi (compression), of each piston? Perhaps loosing engine power from there?

    145-190 for compression take the scom off. If it runs the same then u may have your answer

    It shouldn´t be the Scom but try anyways. The Screen is showing no errors or codes, and it should not affect the boost or limit it to 12 lbs all the time.
