BMW M3 Forum (E90 E92) - View Single Post - Dinan sale today.. Question regarding Underdrive

I thought the S65 has a system that disconnects the accessories during wide open throttle. This would mean the pulley's won't be as effective. I have heard of people having problems with their electronics as well, I would stay away.
