but yes, Pay to Play I get that. No tear here if something goes wrong by my doing.
I mean, that's just ethically wrong. You are welcome to live your life that way though, I understand the desire to.

This sound is not exhibited on turbos that haven't been abused. This sound comes from over spinning the turbos and driving too much PWM through them. That is the cause. That isn't to say there aren't a couple defective units out there, there is no way to know really, but 99% of the time this is caused by overboost.
