You will struggle to find anyone who spun their crank hub on a stock tune no matter how hard they drove it.

I am tuned, though. I'm not too stressed about spinning but it seems there is something to do with drive settings as manual cars have a much lower prevalence of SCH. Maybe I'm thinking of it all wrong but in my mind the situation that would cause the hub to want to spin is from quickly changing RPMs. The harmonic balancer/pulley wants to breakaway(spin) from the crank due to a sudden change in engine speed. The inertia of the pulley/balancer/valve-train makes matters worse.
Perhaps tuned cars are able to spin up RPMs/shifts faster and that's what causes more incidences. Idk, I'm just spitballing. If it's a fact that DTC has a higher prevalence of SCH, then I would think shift harshness matters.
