Keep in mind they did not beat hard on the Z in mag testing, they even say so in some of the articles. Again with 138K miles on the cats and a corsa exhaust my car ran 12.88 112.68. Its the launch rpm that gets you deeper into the 12s.....Johnny 5 your car should be 12.4 or so at 117+...the issue us the more power the lower RPM you have to launch on street tires which is why you see a 27+ MPH pick up on the back end of the quarter.
