    and now i am loosing boost under power it will drop RPM and boost then come right back but dose it a low and high speed but it feels like the time i 100% fucked my ring and impeller like it bogging down and not going no where then it comes good

    Welcome to the forum mate. Have you contacted Riva for them to log in and check your tune? And have you checked your pump and impeller?

    ok i now have the pump out the ring looks fine a few small grooves and scratches nothing major but the pump seal looks like it was pinched and was sitting off a bit when i pulled it off i dont know if that will do much or not prop looks just as new as when i got it

    It should be hard to spin by hand. There should not be easy and hard spots, it should be very stiff.

    Your slip on the s/c needs to be checked and probably reset.
    You shouldn't be able to turn it easily.
