I looked at powerchip then decided to go with REVO Technik software instead. Revo's software is flash loaded meaning NO swapping of computers, or soldering in a new chip such as power chip.
You can even have a FREE 4hour test program of the REVO installed! I tried the FREE trial and loved it. Improved throttle response and noticable more power. Plus it only took 15 minutes to install at the shop

You can also look into GIAC, or
www.goapr.com they have software too, but REVO is so plug and play it is my definite option.
