OK yeah I kinda had that look just now! I did and it was. Hmm. I learned something but can't quite word it. The floating relationship between advance and KR reminds me of the one between LT and ST fuel trims, and on the fly it works out so she runs perfect. Almost perfect, so yes headers and all that with a tune... man you got a hottie! The advance curve is just wicked agressive by carb n dizzy standards. More study needed but small aha moment, thanks for that. Seriously though, as a daily driver... I'd get myself in trouble with much more than what I have. Comes from a lifetime of slow stuff.
