Running great, then it wouldn't go above 7200 rpm. No codes.

I would say there is a exhaust valve issue, where they for some reason is not opening or there is an issue with the sensor reading the exhaust valve movement.
If the sensor says the valves are closed the engine will not rev above 7200.
The Rave valves were my first thought as well. The dealer was thinking maybe a fuel pump, or maybe the ECU...

There's a part called a manifold that has vacuum lines running to it, it's part of the rave system. Have your dealer hook up the sled to the buds system and start the sled on a jack stand. Check the voltage of the raves at idle and then watch it as you increase the throttle to make sure it stays in the ranges. Mine was showing the voltage at half open at idle, once the rpms got up and got the voltage in range it ran well. Might not be your problem but a stupid cheap part that can fail.I have the same sled and is at the dealer right now. First time it was in they found the fuel pressure regulator gasket was bad and I was not getting enough fuel pressure which was causing a hard start issue and poor running. Next time I took it out it wouldn't turn more than 6800 rpm and the snow was deep and we wanted to ride.
Cranked the clicker to 6 which did bring RPM up along with blowing up a belt. Chalked it up to the prior belt being bad so put on the new spare and turned the clickers back down to 4 and the sled seemed to run ok for a while. Then started having all kinds of weirdness. High idle, not able to go in reverse, hard starting.
Not sure at this point. Will let you know what the dealer finds out.
