Selling my Thundermax. Put it into my 117 and apparently had some slag in the new exhaust that was installed at the same time so the top end got jacked up from the reversion. Had a crate motor installed afterwards and I won't be using this. It was used for all of maybe a couple of minutes. Clean unit including the ECM, both 18mm Bosch wide-band O2 sensors, the USB communication cable, and original packaging. $540. Will only respond to texts or phone calls.
