OK I think the problem was my Sync 3 upgrade and the fact the FCIM was from a Fusion, and the radio is one I bought on Ebay with XM capability. I downloaded my as-built (.ab) file from Ford Service for my VIN, and used AsBuiltExplorer to identify differences in ACM between what's currently in the car and what it left the factory with. The original ACM values were as follows, which are different from what Forscan was reading:
727-01-01: D800 2800 0030
727-01-02: 0100 32
727-04-01: 0003 0255 53E0
I reflashed the car to the above entries, but for 727-01-02, I entered 0000 32 (Forscan automatically corrected the checksum to 0000 31). IMMEDIATELY noticed improved bass and volume. Checked the sound levels on the same CD song at volume 10 as before, and the sound is up from 48 avg / 56 peak to 70 avg / 78 peak! Unbelievable change. Turned it up to about 16-17 for a few seconds and my ears have been ringing for the past hour! Reversing my thoughts on these Kicker 43DSC6704 speakers, they are awesome, almost feels like i have an amp and subwoofer now! HIGHLY recommend them. Can’t believe for $148 and a programming change it sounds like the Bose system in my Silverado.
There are a lot of DTC's showing up in Forscan, again I'm sure because of the Sync 3 upgrade, so now I'm going to go back and compare my VIN as-built's to what's currently in the car and hopefully knock a lot of those DTC's out.
