FAST Electronics recently announced an upgrade to their race-proved XFI Fuel Injection system which adds new functionality to the popular system. Perhaps the most significant advance in the FAST XFI 2.0 system is the addition of self-tuning capabilities. What's even better is that you can send in your existing FAST XFI 1.0 box and have it upgraded to 2.0 at a surprisingly low cost. We spoke with FAST at the International Motorsports Industry Show to learn more.
