Lew, sounds good... I will be datalogging either today on my way to work or tomorrow which I am off. and then I will either create a screen name or find my old ids and get in so you can help me do everything else. I appreciate all the help. Thanks...

You can say I am a newbie when it comes to tuning... I can build you whatever you choose but I have very to no experience in working with a Predator or tuning a vehicle using one. I think I downloaded everything needed... if not maybe even more. I have a 2005 LS2 6.0 with a Airaid CAI, NGK TR6's and ...

ok well i removed the cats about an hour after I wrote the question about the Check engine light and I realized that there is "NO" rear O2's on my vette... there were just the O2's that are on the manifolds and thats it (those are before the cats) and there are only 2 cats so no "CHECK ENGINE" yet ...

I am about to go have the cats removed and I understand that I will be getting the O2 failure code, is there a way I can remove the code using my predator? I think its the 4171 i have. Any help will be appreciated. Thanks in advance.
