Wayner, I can't answer your specific question, and I don't think of CIS as "good" (I think it is a royal pain in the arse to trouble shoot and customize, that utilizes way too many band-aide-style add ons to function well), but I do know that CIS can be set up to support serious power - many of the 934s ran highly modified CIS back in the day (big power, buttofcourse), and currently there are those that are going beyond 400hp with their CIS fueled Turbos (400+ requiring substantial modifications to the system, however).

I've also read the claim about "emissions" being a driving factor for CIS, but don't understand that at all considering how wasteful the system is - it keeps dumping fuel even at initial closed throttle, among other shortcomings!
