The graph shows a calculated 92% drivetrain efficiency, so the actual measured HP is about 348.

I remembered that Z1 motorsports makes a package with a cat, CAI and other intake and exhaust manifolds that makes 425-ish, my 379 is not even that strange.
The Z1 package isn't whp, it's crank hp. Your number is high for the mods you have - what's a stock Z put down on their dyno?
