Anyone use a DF-17 adjustable PCV?

I recommend everyone run a PCV valve AND they get the Wagner valve and be done with it.

I suspect that this valve would fix my tip-in lean spot. It's just as the throttle starts to open. No amount of messing with pump linkage, squirters, t-slot restrictors, IFR etc. could completely get rid of it. I think my "whatever Autozone PVC valve fits the cover" is causing the problem since idle vacuum is already only 8".
