Precision certainly had some major issues when Garrett first cut them off. Their current generation of turbo's I would have no issues running.
They are one of the current favorite turbo's of the 2.6" inducer sled pulling class, I don't know that there is a more abusive form of motorsport to a turbo then a class limited by turbo inducer size. Where they push these things to 80psi+ on a single turbo, with almost inconceivable shaft speeds. Obviously there are failures, but no more then any other brand.
