I'd be more upset there are 370Z's that made like 20whp more on that dyno with just i/e and tune
TAKE THAT JULIO! JK of course..
It's weird though, didn't look like you LOST power, but it does flatten out. How does the car feel? I mean, you rev until 8k, you're going to fall more into your powerband and it should move nicely.
