Two days before the accident, they departed and planned to climb to 10,000 ft and utilize the turbo system, but the engine was not developing full power and the manifold pressure was low.

The pilot told him he had completed a checkout in a PA-24 in Texas, but it was not equipped with a turbocharger. According to a flight instructor, the pilot had recently purchased the airplane and wanted to fly with an instructor to familiarize himself with the RayJay turbocharger system before flying home to Texas.
