Did you ever get that boost sensitive WUR hooked up? I was just wondering how it affected things. Even if it doesn't help out on top I'd like to try one to see if it helps throttle response. I hate that dead spot right when you want to go fast. My car seems a lot more responsive off the bottom when it's cold. I spose this is due to the lower control pressure.

Yes... but I'm not sure what it was doing exactly. With it connected my mileage was reading 8 litres per 100 kms. With it disconnected (just did that over the weekend) it is closer to 10. I present that data just as reference. The weird thing is that the fuel mileage was horrendous with it connected although it reads better. Disconnected the mileage reads worse but is improved. I'm going to read that CIS *.pdf that was presented a few posts back and see if I can make sense of it. So far I am reasoning that the increased pressure at the shimmed plunger when combined with the WUR connected results in way too much fuel based on mileage figures only.

Under cruise (vac.) it is supposed to increase control pressure and result in leaner running. Under booost it should lower pressure and result in fuel enrichment.

Perhaps the WUR you got is bad. Did you do any checks on the fuel pressures? That's the only thing I can think of. How does the car seem to be holding up under high boost?

but does seem to have a bit more kick with the line disconnected (as judged by the 'Seat-O-Pants-O-Meter'.
