The turbo was replaced before I bought it. But what I was told is that it was a new factory replacement. Definitely not an upgrade.
Sounds like my suspicions may be right, that this thing is set way high for some reason. I’m going to adjust down to about 5 and see if that solves my problem. I’m suspecting it was messed with.
