Pretty good info in here, thought I'd pass it along.

"Precision is a company that up until recently was really just a distributor of Garrett turbo’s. They would take Garrett turbo’s and resell them, mainly focusing on the aftermarket scene. Then they started to modify Garrett turbo’s and openly advertise how their turbo’s were out performing standard Garrett turbo’s. As you can guess Garrett wasn’t happy about that. You would have to assume Precision as a company knew what they were doing. We have all heard the saying: “you shouldn’t crap where you sleep”. Garrett then cut off precision as a supplier."
