It is my understanding that Bolekous Dynamic developed a milder version of the Automatic SB for the MB crowd.

(ie BDD541A2)
The Manual SB version is the most aggressive version, but you could install the Automatic SB (BDD541A) in a Manual Transmission Vehicle to get a tamer/less aggressive throttle response.
However, you should not install the Manual SB version in an Automatic transmission vehicle.
Hope this helps dispell some of the SB questions!
