Regarding Craig's point on the IA head:
I realize that my SC and the 930 are a bit different, but principally the same. I was unable to get AFR's below 13:1, even with the old homemade adjustable SC WUR. The IA mod allows a lower AFR (they told me they could get a point of AFR with the mod on my SC fuel head, and they did). The Brian Leask WUR seems to make the system way more compliant and tunable. I tend to agree with Craig on WUR first, then fuel head mod. I have no experience with Brian's RPM switch. I would like to know what the difference is between the RPM switch, and the boost threshold adjustment on the WUR.

I can say that my street AFR's are just right, but I was 10:1 AFR on the track for the past two days. My little engine was on boost basically all the time, except for the corners. I may be able to tune that with the WUR. I'd like to know what you guys are seeing on the track.
