Tunnel Ram Tune

Hey folks, just going to throw this out there. Posted on a different forum and thought why not here too.

I'm looking for some direction in a lean condition at cruise. I suspect it is related to the transition between the end of the transition slots and the beginning of the mains coming on. I can feel and hear the engine going lean and flat in the cruise range of 50-60mph.
35 1500 14
45 1900 15.5
55 2250 16.5-17
65 2800 15
70 3050 14.5
It runs and feels good in the 14-15...
