Note the comparison is based only on pressures and not all other variables like volume (CFM), temperature etc.

Yep, running 15+ in my wrx and it's a much lower compression engine than my LS3. Not really amazing or interesting that the mustang runs 15, it just most likely has a compression ratio to compensate so that it's not being torn apart by detonation constantly.
