i removed the catalytic converters with an off road x-pipe. do i need to reconfigure any thing? it also has a k&n cold air kit and flowmaster mufflers. any help would be appreciated.
thanks

The cold air kit is an easy issue. Just install the K&N cold air kit tune that is in the tunes menu. As for the off road x-pipe You will have to have a custom tune done for this mod. The EPA made us remove the ability to turn off rear o2 sensors. You would have to contact one of our CMR dealers to have this done. Or you could contact bamachips.com or tuningsuperstore.com via the web.
