GMPP LS3 Contoler Kit...Fans, am I missing something here?

So I have several customers that are using this setup in trucks. I have had multiple complaints that the fans are turning on and never turning off. Has anyone come across this yet? The instaltion guide states that the fans are supposed to turn on at 207, in wich case the thermostat would be allowed to do its job. This does not seem to be the case. I went through the tune, updated the checksums and did the cooling fan operating patch. Now it seems as the fans are coming on around 160? Is there no other adjustment in this operating system?

The first tune is the stock one, and the second is the updated one...any ideas???

I think the fan control tables are missing in the GMPP OS, well they are there, but not shown, I can't recall why they weren't added.
