A footnote to 911st comment.... I am using a 054 WUR on my 77 rather than a 112WUR typically used for the '75-'77 930's. The 112 requires vacuum to lean after initial warmup. Brain Leask suggested I send him the 054 to modify rather than the 112. After installing the 054, I just plugged the vacuum hose from the throttle body and obviously still using the boost enrichment side of the WUR. The 054 vents to atmosphere. The beauty of the adjustable WUR is the ability to lean or richen certain aspects of the curve, cold and warm. There just isnt enough adjustability in the idle mixture screw.

I ll run the rest of the winter and spring as it is and will check ide c/o % when summer rolls around.

Drove to and from work today, mostly fwy. Car ran fantastic. Boost seems more linear than before. i logged more than 65 miles on less than a quarter of a tank of gas. I am thinking somewhere around 17mpg's , maybe a little better.
