At 38k miles it's just broken in. HP should be all there. Ask about the ZHP specific torque dip at 4K RPM. Software-related, and to the more aggressive cams.
Ask about oil changes (often hopefully) and crankcase ventilation upgrade kit, if it's been done.
I love my Dinan ZSP

I love the e46 design. It's clean and efficient looking, with nothing extraneous.
