Like all the others experiencing major-league vicarious thrills watching this unfold, I can't thank you enough for all the effort and especially for your generosity in sharing this! What a guy!
Question: I wasn't certain if all of the manifolds were port-matched for this round of testing? And what your protocol is for doing port-matching? Sorry if you covered this already and I missed it.
With an RPM on my heavy-duty truck now, I'm a little dismayed and surprised to see the "stagger" at low rpm's. My "seat-o-meter" swears that the RPM runs consistently stronger than the Performer 390 that I used originally, tho not as pronounced in the lower range.
Also, any chance you might try a 1" spacer as a variable on these runs?
