Long tube headers throwing 02 codes like crazy ?

Just installed my long tubes and i keep getting a p1133 code for the front 02 sensor not switching fast enough and now 0420 and 0430 for the from and back reading to close to each other. Truck idles rough and hesitates on takeoff.

Thanks

those are normal header codes and you need to get a tune to turn thr codes off.

i never had any codes for the front 02s with headers though... the rear ones just need to be turned off in the tune. and you can prolly swap the rear ones to the front if you have a problem
