Well...this is a tuner thread sooooooooooo.....Go with the Xcal 2 or the Xcal 3. Both are great I have the xcal2 with a CUSTOM TUNE. My mods are very similar to yours, and I got 20 Hp and 20 TQ out it. click on the link in my sig. It will take you to the place to go to get a tuner. The guy there gives the best prices (especially to MM members...let him know that you are one). He gives you free usb and data cables, and he gives you FREE CUSTOM TUNES FOR 2 YEARS! He really knows his stuff. Just check out the website. It will be able to answer a lot of your questions.
