BTW,when tuning for cruise, you tune the PVCR and not the main jet.

Let me say it this way...set your cruise tune with the main jets. Trim the mains down until you get the cruise perfect, and then tune for WOT with PVCR and power valve opening. Once the opening is set, you don't need to screw with that. Tune cruise with the main jets and WOT with the power valve.
