I was using an electric boost controller of my own design (basic, on-off solenoid driven by a pressure switch), but have yanked it out in favor of an HKS unit I recently bought. Just need to finish the installation and try it out. So for now, I'm stuck back at .8 bar.

As to AFR's with variable boost, it seems that my AFR's drop as the boost builds beyond the stock .8 bar. That's ideal, 'cause I want the extra gas when pushing the envelope. My WUR was originally set up with 1.0 bar boost in mind.

As to the stock magnesium recirc assembly....well, I've pretty much deviated from the norm on that one. See the following thread:
BOV update with short neck IC
Mark H. 1987 930, GP White, Wevo shifter, Borla exhaust, stock everything else. The result of a massive Pelicanite good will fire recovery effort. Truely an open book, ready for the slippery slopes to modification.
