Refining Long Term Fuel Trims

The long term fuel trim for the tune I have been using with the Turbo Concepts Stage 1 turbochargers has been off a bit for the Partial Throttle condition.  Values have been high, but not high enough to throw a fault code,  finally after driving with the trims elevated for a while I decided to do something to bring them down.
