hi guys in my dyna 07 i have vance straight shot slip ons, fuelpack,and airfilter, stage one, i would like to know,do i have to bypass the 02 sensor? or i can let those work stock thanks for your help

 

If you're talking about the sensors that screw into the headers than yes you just forget about them.

 

Leave the oxygen sensors alone. They remain in the headpipes as they come from the manufacturer. Read the FuelPak instructions. They are clear.

 

Because the Fuelpak is EPA compliant and technically street legal it uses the stock O2 sensors.

Some people have no problem with this but I was getting some heat issues during highway cruising and some popping here and there. Things improved alot when I installed XiEDs from nightrider.com

 

i bypassed the stock sensors and just used them to plug the bungholes.

 

thanks a lot guys, ill leave the 02 sensor like stock, but still i have some popping in decel my setting map is fp 0602, i talked with vance and hines service they only told me to change the mode 23 from 16 to 15 but nothing change
