With a turbo engine I would drive with some instrumentation to start with so you build muscle memory for various rpms and torque request. You basically just do not want the engine to run super rich at high boost, and you might be surprised how easily it will get to the enrichment zone if you haven't watched a lambda gauge.

Shift point is mostly unimportant as long as you keep the engine efficiency high as much as possible. That means a little below the highest torque you can get while still running stoichiometric, and use as high of a gear as needed to avoid running at low load.

If that wasn't concrete enough, get Torque + an OBD scanner, stick your smartphone on the dash, and learn to back off if the AFR drops below 14.7.
