I hate to say it, but I've run mine @ the track and at that time my best was 15 flat @ 93 mph. I staged @ 3,000. I think I could have gotten 2 or 3 more tenths by staging @ 3,500 to 4,000. I also think you have to shift it @ 5,800 or a little less. I took mine to 6,000 and its hard to hit it right @ 6000 before you hit the limiter. I only had 2 - 3,000 miles on the car at the time, I'll try to go back soon and see if I can do better. I agree with Bullseye and X'ed those cars have to be driven just right at the launch, otherwise they bog down real fast.
