I curently have a # 4 lower last time i dynoed it it had a A/F of 11.6-1 just about clear across the boards, i was wondering how much a difference in A/F would it make if i was to go to a # 5 or even a # 6? I was just wondering if it would be enough i would need a reburn, if i could just lean it out to 12.0-12.1 or so i would just leave it alone. Any ideas on how much 1 or 2 more pounds of boost will change things
