My owner's manual says that no-load revving of the motor near 4500 will cause cut. Maybe it is just that?

I stand corrected. I just wish it were higher

Its probably not a bad idea by Nissan to cut it short. Generally speaking, free revving the engine without any load will make it easier to float the valves since you can rev up so quickly.
