So I've had a test pipe on for about a month running stage 2 on Cobb and I got p2096 (which I cleared with the AP) is that just from having a test pipe? I recently put on a down pipe ( like within the last few days) also. Thanks in advance!

 

Logged some pulls to see if I was in fact lean, and i'm registering little to no knock.. so I'm assuming it's just a leak between the two O2 censors making the last one think i'm lean.
