Nice find on the TPS sensor for a very good price, I can't seem to find it for that cheap though https://shop.advanceautoparts.com/p/wells-vehicle-electronics-throttle-position-sensor-tps213/10305490-P is this it at $66.99?
As for "fuel cut on decel" function, it is said to pull somewhere between 5%-10% across the bottom two rows right of idle RPM, since it works in the background this was a best guess from either Mike Cobb or Gemini, both of which have massive amounts of tuning knowledge of these bikes. The engine braking forces can go up drastically with this much fuel removed, I myself thought I would like it more aggressive but turned it back off after about 3 days... the better option is to just pull fuel in small increments (1%-2%) out of these rows, think of it as working on a slide scale from the stock decel to the more/almost to aggressive decel you get when checking that box.
Also before you start going crazy with tuning the maps I suggest you search "square idle" and work on that then move to data logging for map adjustment. Some other things to consider are I think you said your AFV is in the 116% range right? You need to see what the highest cell value is in your fuel maps right now (pre-tuning) and keep in mind the highest value you can ask for is 255! Your ECM may already be asking for more than 100% possible fuel.
Here is an hypothetical example: Highest cell value is 245 but AFV is 116% right?
245 value is at the assumption your AFV is 100%, 116 divided by 100 is 1.16, 245 times 1.16 is 284.2! But at a 245 value 100% AFV you only have 1.04% more fuel to offer up!
If you find this to be the case you can change the FPR out and globally back the maps values down to compensate, giving you more headroom at the highest values.
