Surging at light acceleration

[442w30]

Hello everybody, I just received my Gryphon and am really impressed "But" have a question on surge. On very light acceleration 3rd gear TC not locked the truck will slightly surge, not really a lot but just enough to get your attention. Once TC locks surge goes away. My 08 5.4 is stone stock using level 2 87 tow setting. I have not changed any of the settings, it is the way it came out of the box.

Was thinking about unloading and just trying level 1 Trans only to see if it still does the same thing ( I mean surge).

John.
