I bought my TORS on this site, did the reset and it ran ok. Just a little gurgling in the exhaust. It got worse, so I did the Tune ECU for the TORS and it has been awesome ever since.
Talking with these guys, the K&N under seat is a waste of money. If you want real power, get the three individual K&N with the TORS and download the tune for it. The tunes are free. For insane power, get the Jardan's with the three K&Ns with the download. Many guys have added a Power Commander. Just remember, more power comes with a MPG loss. Good luck.
