Anyone who has tuned a sportbike and been promised huge gains compared to another product figures this out quickly.

Then you haven't been involved in the BMW tuning world long enough. For years the tunes for the E46 M3 were lucky to make stock power, let alone make power. Most of the "tunes" just changed the throttle mapping for the illusion of power(eg, BMS Powerbox for the N52). Evolve came along and posted their tune, claiming a 20hp gain. Almost everyone, and rightly so, assumed it was BS. A few people tried it fortunately, and found the gains to be real.
The difference was that while some were tweaking values for their tunes, Evolve was fundamentally rewriting the code behind the tune. They aren't the only ones who are capable of this(Polar comes to mind), but it is an approach very few take or are capable of taking.
And the end of the day though, this is all just words to you and you want to see a dyno. It's not a problem and I understand. Soon enough.
