I have mine chipped last 2004 and to be honest, I'm still wondering if there is really an ECU software changed in my XFIREX. Since until now Upsolute still don't have the Crossfire in their website database. When I have mine installed in 2004, the guy that did it even have a hard time installing the software or I'm wondering what kind of software is installed. I can't really feel a big difference and I'm wondering if I wasn't being scammed regarding this. There's no paperwork or dyno testing to support their claims. Most of our claims around this forum are just subjective opinions about it and none has dynoed it so far.

How do we find out if your ECU is chipped or not?
