The Thundermax does everything it's supposed to. I swapped it out with a TTS Mastertune, got better results for my 113 build, and now I'm selling the Tmax.

The Tmax was installed on my bike from July 2008 - May 2010 and approximately 10,700 miles of use.

I've removed the electrical tape to show some signs of wearing. Please note, I do not have the original box but manuals and software are available online at
