Hey guys I have the p0420 code on my 07 car only has 21k on it so I highly doubt its a bad cat. My local dealer wants 150 bucks to flash the code which imo is stupid since its not a wear item, its glitch by gm on all car models, but I digress...

So my question is can anyone help me out here that has had the update done and send me an hptuners file of the car after the changes were made??

This is an emissions thing covered by the emissions warranty which may still be in force on your car. The first time my car got this the dealer replaced the cat and the exhaust manifold they broke. The next time I brought this notice in, they reflashed the ECM and I've not had the problem back. I was under normal warranty then.

Thanks for the reply man I wish that was the case. The cat warranty is 8/80k so it's about a year out :/ that's what I originally tried lol
