Check your codes first and let us know what you find..

Try describing your problem better..

1) Is your turbo not spooling or is it over spooling?
2) describe when and how the car "turns off" on you.

For example: (after starting is a given), after boosting, after you let off the gas at the stop light, when the car is cold, when its warm? More info please..

TPS (throttle position sensor) or ISC (Idle speed controller), both should not cause boost issues but can effect idle and or base timing/performance..
