So I figured the 24 HG is really 12 inches @ idle, seems pretty low, but I think that is because the timing is retarded?

If your W.O.T. runs will get richer by increasing the PVCR larger,,, I would drill out the PVCR to the minimal increase in size, you are way too lean @ W.O.T., & if you are going to run more boost pressure, it will be even more lean.

Just do one adjustment @ a time.
