Undetectable tuner

Closest we can know is to use PuttNutt24's SE447 which used an aftermarket exhaust and aftermarket tuner, and compare that to what FuelMoto got from their 114 with aftermarket exhaust and aftermarket tune. Even then, it's not a direct comparison because it's different dynos and different guys running the dyno.
From what I'm seeing on the FuelMoto page, all the cams seemed to have generally similar curves, peak HP from 110 to 118 and peak torque 120 to 126. Compare that with PuttNutt's chart, 111 HP and 129 ft/lbs. That's the SE447 torque cam, and it delivered more ft/lbs than any of the aftermarket cams. HP was on the low end. Seems like what you would expect, right? I imagine that if PuttNutt24'd gone with the HP cam, the opposite would be true, HP would be on the high end of the group and torque toward the lower end.
That's the closest comparison I can find on the web. It shows the SE447 as being generally comparable to the aftermarket cams. But the only true way to know would have been if they would have included the 447 in their overall test; without that, we can't know what variables don't line up. I understand they didn't want to, I don't begrudge them that, I'm just pointing out that we don't have a direct apples-to-apples way to compare them now.
Screw that!
I'm not one to defend the MoCo, but the above is the truth. With the size of these motors if the MoCo spent any time developing them they could make a lot more HP and torque and be reliable. Then we would not have to figure out how to get the power they should have.
