Monte, thanks for that Insight,

I was kind of thinking that Holley (eventually) will try to consolidate and either wholesale adopt whatever turns out to be the most Trouble free and profitable system or (And I don't think the Venture Capital Investment team that runs Holley will spend the time to do this) try to marry the best of all the systems and come up with some 'hybrid' replacement system.

I'm impressed with the Atomic that I've seen, particularly that it took less than 40 minutes to completely swap from the 4150 to the efi On the Dyno and make a pull.
