Just pulled a tough hill, towing my about 17k 5ver, pushing it hard to get past a wide load truck and the turbo went to about 20,000 or so... pretty loud wind up noise that is new to me. Wondered if ...
Well there ya go... perhaps it's boost pressure... told ya I'm a novice with this engine... got too used to Silver Leaf with way more information than necessary as my wife used to say... can't have too much information now can ya???
So it sounds like its no biggie... sure pulled the hill well that's for sure.
