Back when I ran my 454 with a small blower 5LBS back in 1988, No way to log AFRS other then read the plugs,I had a 850 Holley boost ref, running 92P 98S, pvs front and rear I have to think oneanddone is lean as well
I've seen where with roots blowers in boats, sometimes being too lean, will slow the boat down, and of course if lean enough, melt some $hit! .
