Engine/Turbo Issues

Ive got 96K on the clock and after my last trip Ive identified some issues. When towing I will occasionally experience power loss. The turbo boost drops significantly usually to 6-8 # and will not go any higher---in a couple of minutes it will slowly begin to increase and in a couple of more minutes it will operate normally again --This has happened before a couple of times --usually several thousand (10-15) between incidents. Now it happens every 500 to 600 miles. No code is thrown.

Ive also noticed a noticable increase in turbo lag not only from inital launch but also at highway speeds when attempting to pass another vechile--

The next issue is an annoying whine in the turbo. The whine occurs usually at lower speed and it is most pronounced when the throttle is "feathered" and backed off slightly. Also the spin down of the turbo is quite noticeable.

Finally my mileage has gone down the tubes. I used to get 12 MPG when towing --now Im lucky if I get 9 MPG--

Since the Engine warranty is up in less than 4K Im taking this to the dealer on Monday Morning to get it fixed--

Any recommendations as to other area that I should have the dealer look at?
