I purchased this 1994 Volvo 850 Turbo brand new in 1994, which was the first year of the 850 Turbo. As soon as IPD began offering their tuning services we immediately sent it away and purchased both the full exhaust upgrade and the engine control unit upgrade. The difference it made on the car was unreal.

The car has finally reached the end of its life, but the IPD Tuned computer hasn't.

While we never had the car run on the dyno, the difference it made was astronomical.

PLEASE make sure this will work on your car. There are absolutely no exchanges and the computer is in perfect working order. This is a very rare opportunity to add a significant amount of power to your 850.
