Acts like it wants to die

Hello, sounds like a possible concern with the air - fuel mixture, perhaps too much or not enough air, such as from a vacuum leak or air intake leak. Use of a diagnostic tool to monitor fuel trims and other important information is essential. I believe that hands on testing by an experienced professional with proper equipment and resources will determine the cause of failure without much trouble. I don't see or feel like there is any correlation of the turbocharger to the air conditioning compressor. However, a second opinion can be helpful with hands on testing.
