I beg to disagree...

I also had issues with CIS, and honestly diagnosing it is a PIA. For me it was incredibly easy to bolt on a set of 40mm Webers, order all the venturi's and jets from PMO ( their recommendations based on my engine - early headers and sport muffler ), and bolt it on.

The car has night and day better throttle response than it ever did with CIS, starts and runs faultlessly, and feels like it makes more power. The car hasn't been on a dyno, and had no further tuning. At some point in time I'll do pistons and cams and probably then do some dyno tuning.



Cheers,
