    I had C-3 before and was at 80 mph. Now I have 2 problems not enough fuel and my BOV is opening up and won't stay closed so I might be boosting more then that.The diff from C-3 and H-1 is big before at 13lbs ski was quick now it's serious fast.

    Run it with the seat off at WOT and see if you can see the BOV open. Its the only way you'll know if its the BOV.

    Make sure you do it down a nice flat lake......... if you know what I mean.

    Sorry EDIT, read above.
