RickyHanna... I've done the Upsolute chip and it's working Fantastic! It's also about $200.00 cheaper and in most cases you have a rep in your area to take the car to, to get it done. Or if you decide you don't like it you have 30 days and you can take it back and it will be reversed and you get your money back. There are several threads here talking about the Upsolute chip and it's effects. You can also go to www.upsolute.com and get all the info on the chip to include finding the dealer closest to you. With Powerchip you have to send your ECU to them. They chip it and send it back to you and you install it.

Enjoy.
