having a little issue...

so when tuning would u first just "drive" not accelerating to see if primary jetting is correct and then accelerate with secondaries disabled?

same for testing secondaries?? minus disabling primaries of course

and my pv was a 6.5. kinda high because my idle vac is only 11 or so right?

the power valve opens at a given vacum drop/rate and feeds the main system, in your case the pv would open at or below 6.5 manifold vac.

at cruise there is a lot of vacum, too much for the pv to open.

to find the correct rated PV is to know the manifold vac reading at idle in gear, a/t uses the half of of the manifold vac reading with m/t being only 2 rates below manifold vac reading.

so if you have 8in vac at idle in gear [a/t] you would want a 4.5 power valve, which is half [pretty much] of the 8 in reading.

jetting is simply going from ootb, considering elevation, and leaning till a surge at cruise then go richer 2 jet sizes-primary.
If you have a PV in both pri/sec, then you just square up the jetting=same pri/sec. If you only run 1 in the primary, then go 8 jets bigger on the secondary.
