The pack comes with a tuning tool (to install the performance tune). It turns out that the tune, besides adding hp and a more aggressive throttle, also provides the ability to calibrate the speedo by inputting the true circumference of the tires. It also allows calibration to fuel octane. The tune is designed to work best on 93 octane gas. That isn't available here. I can get 92. Apparently in some places only 91 is available. If that causes spark knock, a simple setting on the tuning tool allows optimizing for 91 octane gas. All this without affecting the warranty.

They also offer suspension kits. Unlike the others, the kits include factory-matched parts that provide optimized improvements in handling. The prices aren't crazy either. The performance pack I bought cost me under $600 from an online dealer. Dealer install will be under $200. That is necessary to keep the warranty on the performance pack (3 yrs, 36k miles).
Wow, that is a great price and very cool from Factory! Way to go Ford.
