That was a suggestion I floated some time ago if you recall, but in combination with an rpm window switch and vaccum sensing relay, and a stock boost reactive WUR. Set the window switch to activate and deactivate at something like 1500/3500 rpms and tied in series with a vacuum switch. Operation of the Andial frequency valve would occur immediately once vacuum is seen AND the pre-set lower rpm limit is met, and would deactivate once 3500 (or whatever programmed) rpm was reached....just in time for the WUR to start enriching as boost builds (all dependent upon the turbo being used and how fast it spools). Net-net would be a controlled stepped enrichment through the entire power band.

It just so happens I still have my Andial enricher still installed but no longer using since my Leask WUR provides all the control I need. May just have to scab together the rest of the parts and test out the theory.
