Here the data from Bren-Tune (below):
Looks like +11 ft. Lb. Of torque and + 9-hp (if I am reading these correctly).
So, according to both of these (2) Dyno tests: about +15 hp and + 15 ft. Lbs of torque (Not quite the 20 the OP is looking for).
I have to tell you, the difference after each change was noticeable, and the running temperature of the bike is now 20% less (which was very important to me for longevity). BTW I ran the headers for several months before adding the Bren-Tune.
I understand that many here are perfectly happy with the stock RNT specs. But these changes really improve the bike. The Bren-Tune also eliminates any hesitation(s) or lag. I can now use 5th and 6th gear (and actually accelerate in those gears), where before, I rarely used 5 or 6th.

The baseline is both RED lines, the BT Moto Stage 2 Flash is represented by the BLUE lines. You can see large gains over the entire RPM range and with the extended rev limiter, you’ll have less shifts at the track.
STAGE 1 vs STAGE 2
GREEN = Stage 1 Updated (88whp / 79wtq)
BLUE = Stage 1 (82whp / 74wtq)
RED = Stock (79whp / 68wtq)
You can see Stage 2 exceeds the gains from Stage 1 across the entire RPM range
