Hi Guys, I contacted Vance and Hines on their website to explain to them the only reason I bought there system was the online instructions failed to mention disconnecting o2 sensors. I work in a OEM dyno setting and we run 4 o2 sensors . Two production sensors and to fast feed back sensors. I saw the FP3 still used the factory sensors. And since there online instructions failed to mention disconnecting them I assumed there were still being used on the fuel pack sold for my 2013 Street glide. Well they informed me this March 2016 FP3 for 2013 and earlier touring bikes will be available.
