I think that alone gave me a high chance in achieving my goal of 550whp. I do also have a tomei titanium single exit exhaust. I don't know how much of a difference it would have against a dual setup. On top of that when it was getting tuned, the weather had a nice chill that day. Roughly 40-50 degrees maybe less, and then I had Jon Parhams awesome secret tuning skills. 
So I kinda knew I was gonna get decent numbers at the time but I really wasn't expecting to hit over 600 on 9.5 psi at all, it blew my mind. Guess I was just lucky  |
Z1's dyno seems like it runs just a touch high, so that's why you're showing more power on the same boost. They're a great crew, good tuners and a good shop, but their dyno is very marketing-friendly.
