The tuner didn't do a base line run. The reason, he has done many many Zo6s and said without exception they baseline at about 430 hp. Had I ask he would have done it. I didn't in an attempt to keep my bill such that I had gas money to get home.
I do have a run sheet, however, it's in OH and I'm currently in south west FL.
Of the mods have done on my car this is the one am most happy with.
No offense to you or your tuner, but I hate this line of thinking. It makes a thorough comparison almost impossible. I'm not concerned with what A,B,C,D,E car did on such-&-such a day. I'm concerned with what my car did today, before and after. But I understand the reasoning. You for less cost and them for less stress on the dyno. Regardless, judging by Pfadt's reputation for quality (although this is a new venture for them) I have no doubt you picked up a good amount of power. Enjoy.
