In my opinion, you can also use the Pro profile, as it was only created on the basis of 25nm.
If these profiles were a little too weak for you, you would have to lower the “max force” value in iRacing, for example.
However, some profiles do not use the full power of the SC Pro at all.
For example, I use a profile that I then lowered again to 14nm because it was too strong for me.
Here is a calculation example for iRacing, how the wheelbase affects the NM.
iRacing Nm * (WheelBase Nm / iRacing Max Force) = Output Nm
So for instance if iRacing is generating a 10 Nm force and I have a wheelbase with 25 Nm and max force ingame set to 70, the actual force I get is 3,5 Nm
10 * (25 / 70) = ~3,5
To achieve the same output with the Sport you have to adjust the iRacing Max Force.
10 * (17/46) = ~3,5
After this setting, however, always pay attention to the Force Feedback display in iRacing that you are not causing clipping.
Please correct me if I am wrong here with my calcuation.
