I think the PC III would have the edge here, but it would be so slight that it would require a dyno to see it.

I went with the HD stage 1 but I bought it as parts and then bought the K&N at the local autozone. Cheaper that way and you get the K&N instead of the paper filter that comes in the kit.
Should be the same parts for your 07

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.
