[urq] modded UrQ mileage

[Mike Del Tergo]

I suspect you may both be right.  Winter grade gas cuts the mileage on all my Audis.  Keith what is your mileage?  Mine is also a WR but without many of the later bits like O2 and ISV.  It is a Mac-01A.  About 8,000 on the rebuild, but no overbore and standard C:R .  (boy I'd have upped that in a minute If I knew 7 years ago what I know now)  Nothing I can think of to drop the mileage like that.  It is certaily off on summer grade fuel as well.  I have 'closed' the CO screw now almost 1/2 turn in tiny increments and the A/F meter readings virtually unchanged, (showing rich from 3+ PSI all the way through 16) though my idle has gone from 850 to 1,000.
