Out of curiosity, I compared my dyno to a stock ZL1 dyno I found here:
Stock ZL1 Dyno and when I look at the curve, it seems like my car is roughly the same #s as a stock car except a bit better top-end, which confirms my butt dyno.
So all things considered, my $ $ $ earned me sound, got the car running right on 91 octane and got my power levels back up to stock plus a little... Considering all that cost me $4k and I should have gotten that from the factory (except the sound), I'm a little irritated but really like a 1 on a scale of 5 haha.
