This is just "Food for Thought"...

The "TUNE" of the engine and transmission on my 2005 XFR is considerably different that it was on my 2004 XFC.
STOCK condition... and the XFR is quicker and the shifts are more positive.
I even average 26+ MPG vs 24+ MPG...and that is with 2,500 miles vs 10K!!!
DC has done something!!! Maybe this is what the end result is!!!
