CEL light issues
Ill start with the car, 2011 ss l99. Lt headers, no cats, ported tb, injen cai, rx catch can, 1le breather kit, and an underdrive pulley.
All of which was installed roughly 2 years ago. Also got it tuned right after the headers for the 02 sensors. About 6 months ago I started getting random CEL that would come and go. Everytime I got them scanned was the same codes. It seemed to coincide with getting gas. Fill up, goes away. Get low, comes on. So I got a gas cap figuring maybe mine was shot. No dice still get it. The codes its throwing are to do with catalytic system efficiency below thresholds on both banks. Anyways these are the codes. Any help would be hugely appreciated. P2270 P0430 P0420 P2270

I posted on your other thread, those sensors should have been turned off when you had your tune.
