Who can tune this thing right?!

thanks for the reply. I run any where from 100k to 130k so nothing like you have. I haven't had any problems, yet. The turbo does seem to squeal if I come down a steep down grade and start back up the other side. If I back out of the fuel and drop the boost and ease back into it, it stops. I guess it just needs a second to change the vane pitch.
