I've got the 2014 1LE SS with the LS3. And I put a pair of 1 3/4" long tubes on it and I've got a code that says the sensors or switching to slowly for the up stream sensors for both banks.

How do I get this problem corrected? I thought that a flash tune would fix it like it did on the 2010 LS3.

My question is there a replacement wideband or something similar I can get or will I have to get a complete custom tune?
