I just like cruising, don't really care about speed. The TH probably just isn't setup properly for my car. It shifts rapidly and seems to be in 3rd by 15MPH. I can't verfiy though as my speedo is so far off. With this tranny and the 3:73 gears I feel like I'm at a very high RPM range just tying to do 55, which again, I'm not really sure how fast I'm going.
