Guys, the better shifts that you'll get from the transmission are reason enough to buy the tuner, the extra HP/mileage are just a huge bonus. You won't have any more of that lag between the gears. It'll shift nearly instantly, but not harshly. I wish I had gotten mine SOONER actually. If you're going to do one thing to your trac, it SHOULD be a tuner.
It's also very simple to use, just plug it into the port below your steering wheel (you can see it pretty easily if you look), push a button and the thing uploads the new program to your computer. It takes about 1 minute and ANYONE can do it.
I would recommend that over EVERY other performance part that I have. The transmission has a lot of potential to give you great, smooth shifts, but it DOESN'T from the factory.
You'll have to talk to wayne about pricing, but in my opinion, it's worth it, no matter the price. It's like a whole new vehicle.
