).Since you've got a Wideband O2 sensor (which in my eyes is the primary benefit of the unique Dynojet PC III USB with Wideband O2, and why setting the map to all zeros makes sense), give 12.9:1 a try, just for fun, see what you think, let us know.
Also, you can probably disconnect the TPS connectors for the PC III and clean up the look. If you're adventurous, give that a try and see if it still runs. I think it will be fine.

Well I've done about 800 miles with a power commander 3 running 13.8 AFR and map set to 0 as per Rogers recommendations. Well if the AF-XIAD does the same thing all I can say is WOW! The 1150 has always been a grunty beast, but it now pulls top gear strongly from 2,000 rpm and is tractable at ever stage of the rev range. Pulls stronger at the top end too. Returning a solid 46-48mpg too, so I'm happy with that, I'd get a bit more on a long trip I'm sure (I have been a little heavy on the acceleration).
Now, over the next few tanks of fuel It should improve even more,
So how is it going so far, I would echo your initial findings. I'm finding the back wheel cutting loose now when applying the throttle liberally when banked over.
The pickup is much better kinda feels like the bike it should have been out of the factory.
Did you not feel it was good value then?
The above is now on my R1150R, brought from here, it made all the difference to my bikes surging. It made the difference of keeping it or selling it on....
Just back from a 9 day, 2,400 mile jaunt to the med and back, it didn't surge once, at any speed, in the Alps, or in 39 degree heat, it ran just like my old twin spark.
On my bike the best money I've spent, period!
