Need Help with a Sony scd-1

I recently had my scd-1 upgraded from a VSEI level 2 mod to a level 5+ mod. Now after the player goes through it's "loading" and "TOC reading" ritual it just sits there for another 5 to 8 seconds after the first track number comes up on the display before it starts playing. If I select another track before the song ends, I get the same 5 to 8 second wait before it plays the selected song.

Before I had the upgrade done, it would go immediately to whatever song I selected right away with no wait. I know this player takes it's time in the TOC reading of the disc, but does anyone know why it would take so long to start playing after it goes to track 1?
