HELP! 2009 CTS-V running lean after headers and intake
This is my first post here, and I am still learning to use HPTuners. I have a 2009 CTS-V and installed an Air Raid intake as well as Kooks headers and exhaust (with cats). I am running the stock tune and stock O2 sensors. I have bungs for my widebands installed (Innovate LM-2) but have not installed them yet. The problem I am having is my fuel trims are way rich because of the intake and headers causing a lean condition. I don't know enough yet about tuning to redo the correct fuel and spark tables, but I am learning. The car is throwing codes P0420 and P0430 due to the fact its trying to compensate for the lean condition by dumping a ton of fuel. I have disabled those codes, but the problem still exists and needs to be fixed. I don't want to saturate my brand new cats.
I am hoping that someone here can advise me how to get the proper fuel trim based on my tune file and log. I am trying to attach it here for review but it wont let me post the log file? Any help is greatly appreciated!!!!
