    RXT-X 300 dropping to 7600RPM

    Its a 2016 that I put a SCOM on beginning of last season. Would pull to 8000 RPM and hold to 75/76MPH on speedo all day long.

    The last few times out this season as soon as I hit 70/71MPH the rpms drop from 8000 to 7600 and stay there. Feels similar to before I put the SCOM on. Any ideas?

    Intercooler is leaking or it is gunked up with overflow oil and is dirty, change spark plugs too..does it still start in sport mode ?

    Okay I’m unable to go into Sport mode with engine off. Tells me SCOM is not active.

    I put a Riva catch can on same time I did the SCOM so intercooler should be clean.

    Next step is to check the SCOM wiring? Are these things prone to failure?
