My apologies for the late reply. The XFI is still available.
It is brand new version 2.0 literally 1 week old. Bought it on Powertour before i decided to bail on my car.
Has internal data logging on it and comes with the standard plugs and O2 Sensor.
Let me know if you have any further questions on it and I will do my best to answer.
AC Lines have sold. Still have the Alradco fans. These are brand new with the extreme fans, black powdercoated shroud and brand new wiring harness. This is a killer setup and a killer deal for the money. Let me know if interested.
