    Stage 3 RXP slowed to 72mph at 7700rpm

    My stage 3 - 07 RXP with 08 engine ski normally runs 77-78 and around 8k+ RPM and is now only spinning 7700 at 72mph. I have an X charger, prop, fizzle intercooler and many more mods. Has Stainless wear ring. When you mash the throttle around 50-60 it sometimes feels like it slips a bit and is just very sluggish to 70. The holeshot and overall performance of ski is low. Has the RIVA Competition 9200rpm ECU. Any ideas what this could be? I did change the oil recently, I will
    check
    in the morning to make sure the oil level isn’t too high. Could it be The Supercharger clutch?

    "RIVA Competition 9200rpm ECU"

    Riva ECU were 8600, did you have the limit raised?
