I am about to install TSP long tubes on a 01 C5 Vette, I already have HP Tuners but I have never deleted cats before, what DTC codes do I need to dissable?

Thanks Guys.

Bank 1 sensor 2, Bank 2 sensor 2. Everything that has sensor 2, set it to 3No error report, and it will work fine. I tried that for several years until I got tired of the nasty O2smell every time I warm up the motor, and at some stop lights. I installed high flow cats this year. I like the cleaner smell, I would never go back to straight pipes. Still made 480rwhp with the new cats.

Ok thanks, thats what I figured. What about the AIR system I have looked a few times, but all I see are AIR DTC's that mention Bank 1 I don't see any in the list for bank 2 or does it matter since there in only one pump and both banks feed off the same pump?

You'll also want to shut off cat overtemp protection, it won't make much difference other then it just isn't needed. It adds a little extra fuel under conditions were it thinks the cat would be getting hot.

Even with the codes off it will still run the air pump.

Under the hood are two fuse blocks on the drivers side. One will have the fuse for the AIR pump, pull the fuse. That's what I did after tuning till I buy headers and pull it out. Now I don't have to listen to it whine at me anymore
