This thing is great. I installed it on a 2009 Challenger SRT. It makes a huge difference in the way the car shifts. Installation was easy. It arrives in the box with some taps for hooking up the wiring, a USB cable, and a card telling you to go download the instructions.

If you are planning to purchase this product for the first time, please keep in mind that Peachtree does not offer a discount for upgrading. You will pay the same price (or more) no matter how long you have used Peachtree Complete. Also, be prepared to receive countless email and snail mail wanting you to upgrade to NEXT Years product nearly as soon as you install this one. I have never liked Peachtrees business model because I feel like I am constantly being gouged.

I love this stuff. You wont notice anything incredible and in fact you probably wont notice a change at all. I tell people to take to a day for a wekk then stop taking it. You will be able to tell the difference. Its minor, but worth it to me.
