Of course you are entitled to any and every opinion you may have, but I did not photoshop any picture. Maybe you interpreted it wrong?

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?

You're crank HP, not wheel HP. That makes a difference. Most of us here use a DynoJet. Could be the difference in dynos too. From past experience. Your 348 at the wheel is high. Most people with your mods get between 310 to 330 roughly.
