Before changing ACs swap the main jets to something significantly smaller (140s, then 145s) see what happens in the blend area from 3000 to 6000 where the rich dip is currently.
If you have "adequate" size jets then there should be enough fuel supply for the higher RPMs.
I`m afraid that changing IJs will lean out "tip-in" AFRs which are good.
Like we talked about yesterday, see what "cruseing" AFRs are at 2500 to 5000 which is typical hwy driving. On a race car this isn`t as important and WOT is AFRs are critical.
