-Hey guys i need some help. I have a 2017 Camaro 2ss. I have just installed long tube headers with hi flow cats, and of course lol I'm getting codes. I'm new to tuning and I need a little help. I know that I need tom lengthen the delay time of the rear 02 sensors reading do to the placement of the the rear 02 sensors but not totally sure what changes to make. I have disabled all of the rear 02 sensor codes, but I be leave that it will not Compleat a readiness test. I would really like to know the correct way to fix this. If anyone can help I would be most thankful.
