DTC P0133

Ok guys, these codes have been plaguing me since i installed my LT headers P0133,p2195, p2196, p2197. I tried emailing the people who manufactured them but the tech people are not responding to my emails. I tried replacing the 02 sensors twice but still same codes keep popping up.

You need a tune! Has nothing to do with header manufacturer, what happens with long tubes is you move the O2's further down therefore it takes longer for them to reach operating temp but the PCM still shuts down the heater at factory time limit. You also may need defoulers for the down stream sensors even after the tune.

ok thanks that makes a lot of sense, i tried getting a tune through brenspeed but all they achieved was shutting down my MIL so i used my previous tune. Thanks for the insight.
