I have some experience, ran one for a year and really liked it. On roughly anything over 2PSI you want to keep the bp up at least 10psi higher, on mid range numbers keep it around 15-20 higher, top end you can back it off some. These turbos just like lots of bp to keep them spinning happy. As for dyno? No, I know of no one, one thing I did learn with my truck (which is a stick), towing and empty were completely different animals. What would work great empty flat out sucked balls with a load. Once I had it dialed in with a load it was better empty. Then I could just roll some closure out when cruising to keep the fuel use down.
