Sure looks like its out of pump and injectors to me. That 15.2 with the wet system sure tells me that something is maxed.

Tuned two Porsche cars yesterday heading to the 24 Hours of Daytona. Second car was drifting lean beyond 5200rpm. Replaced the pump with a brand new pump of the same size/type (stock replacement) and the car perked up and continued to make power to 7200rpm. All the MW analyzers in the world can't take in to account all the variables. If this guy is really concerned about the health of his motor, he'd get it back to a professional that can diagnose what's happening.
