EDE RPM vs. Weiand Stealth - same performance?

Well, actually I tried the Weiand Stealth against a Holley Strip Dominator one weekend. The Holley was maybe .10 faster, but that was on "MY" particular combo which has a lot of gear, converter and cam duration. Maybe I could have gotten it a bit closer with more tuning. But the impression I got was that the Weiand Stealth would have worked as well or better in most milder combinations.

I did find that the Weiand picked up at least .05 by jetting 3 #'s different between sides with the lower "plane" needing to be richer. I was using a 1" tapered 4-hole spacer on both intakes. I don't know if the same "stagger jetting" would help on other dual plane intakes.
