If you happy with the bottom and middle, increase the fueling under load with the PVCRs, but I would decrease the high speed air bleeds about .004 as a first step.

Not sure what you mean wont that decrease the top end are you saying do this after I jet up the secondarys?

one more thing I switch from a 6.0 to 4.5 I have 0 vaccum big cam at idle

Decreasing the high speed air bleeds has the same effect as increasing the main jet size, but affects the top end more.

So if you happy with bottom end, play with the air bleed size for top end.

Decrease bleed size for less air, richer

Increase for more air, leaner.
