Hey's the brass thing on the inside! As far as how much, that's a TBD and hence the need/requirment for measuring your pressure drop when doing this. The reason you don't want to go to far is the C2 Turbo's WUR is more complicated then the earlier versions and not as easy to tap the other direction if you over shoot. You'll see when you open it up. A 1 mm movement would be a good start. It might take you a few iterations to get to your target. want to go slow, no cutting corners.

Lots of rpm switch's out there...I'd try an ebay search. The newer msd electronic version (8969) looks like you can set the rpm digitally instead of using pills. And it's price is ~$150. You'll also need the valve to redirect the vacuum signal (which you can scavenge from the air pump egr system).

As far as the how to measure pressure drop...that's all detailed in the CIS tester literature. Essentially you intall a gauge inbetween the WUR and fuel head.
