Techlusion TFI on an 08 Ultra

Thanks glider for all the info, you're a pretty knowledgable guy.
Just curious; which air filter did you go with?( I was looking at the k@n 3909).
 
I was told by the tuner at my local dealer that the stock EFI goes quite lean from about 2000-2300 RPM, then it goes richer up to about 2600, then lean again from 2600-3000 or so. He claims that this is because the EPA does their testing only in the narrow bands of 2000-2300 and 2600-3000. Does this sound right?
When I had my 95 inch kit done I had a TFI module put on along with the HD Stage II download.
When done I immediately noticed no more flat spots when accelerating, so the TFI works well as far as I can see. I still get easily 200 miles on a tank of gas, so no complaints.
