Wow, the lightened flywheel must be what's giving you such awesome times! I'm running a 3.91 diff, so I don't have to shift before 60mph. In fact, with the 3.91, I shift into 3rd exactly at 60. I haven't done a proper 0-60 run though. My chip is on it's way and I will definitely be doing some before/after runs and keep you guys updated. Man, can't wait to throw a lightened flywheel on my car!!
