I don’t think it’s detuned at all.
You can’t really compare the dyno runs from two different dynos without knowing the test standard they conform to (if any) as well as the differences in fuel, carb setup etc.
You might be referring to this?
The MRC run gives a better idea as it compares different packages on the same dyno.
One thing you can conclude is that the 175 has about 15%+ power at the peak compared to the S1 supernats winning stock moto.
Compared to a KZ, it makes more peak power, but the KZ has a lot of area under the curve at the upper RPMs.
