Anybody have both? Any problems? ie: reversion Thanks, Doug

1500 RPM Max while the diverters are closed! Or you will get reversion.

Seems a little low. Isn't it AT idle where the potential for reversion is highest? it seems it would be then that the lopiness of the cam could bite you. I have a 600sci with silent choice. Granted, my cam has much less overlap, but I've had no issues at all and have run it up to 3500rpm.
I asked around extensively, including merc and corsa, never got a solid number to stick to. The range that seemed safe was up to 2500-3500.

I have the diverters if you need them.
