This question is very vague. We need more information to help you.

Are you saying that the car responds poorly when the a/c is on? Or that there is no turbo boost at all?

There is no electrical connection between the turbocharger system and the a/c system.

On my 92 the car performance is degraded a bit when the a/c is on, especially at low RPM. The a/c system consumes a lot of engine power, as well as a fairly high load on the electrical system, which causes a higher load on the engine from the alternator.

Estimate are that a/c compressor operation consumes anywhere from 4 to 11 horsepower. That doesnt include additional load from the alternator to run the compressor clutch, the blower moter, and both condenser cooling fans.

The turbo won't just "shut off" like he says, we do need some more information

Does this happen when you're driving? Any other symptoms? What troubleshooting have you done?
