Well, after reading all these posts I had to go for a drive... got to 100 no problems, lots of throttle left but didn't feel like a ticket and didn't have my fuzz buster so i calmed down after that. I was surprised by how solid it felt at that speed, got pretty loud and I forgot to look at the tach. I drive from Dallas to Portland everyday at 80 no problems but I am turning 3600 at that speed with the low axle gears, I think I want to try 4.88's next.

My 0-60 time is pretty lame because of all the shifting that has to happen, I think 60 can happen in 3rd. I heard there is an app I can get for my wife's iPhone that will record 0 - 60 times and G's and some other things, if I can find that I'll post up the times.
