The system is in place to curb torque steer as to the best of my understanding. I tried to look for a couple of minutes to find the file I'd read that best told what was happening but I'm at work and couldn't find it.
The boost is limited to a variable based on steering angle. First gear with the wheel perfectly forward you can achieve a maximum of something like 9psi (whereas boost can drop as low as something around 35% if you're in the midst of a turn), second max is around 12psi, and then third is 15.6 regardless. The numbers are guesses just trying to recall what I'd read in the past... but I don't know if it's a system in place to prevent wheel spin as much as it is to prevent torque steer.
I think what many people's mentality is that they'd rather modulate the throttle under full boost and risk some spin then know that even if they do everything perfect they're still going to be limited in what they can achieve.
I'm not weighing in either way.. just what I think the system is there for and I could see both sides of the arguement being valid.
