P2096 with...

Ok I obviously have an 09 Ss
What I have done?
Kn intake
Hahn charge pipe
Treadstone fmic, tr8
Stock cold side pipe that may have a leak
Bad Mab catless downpipe
And 3" catback exhaust, crush bent for now
And a hp tuners 25 psi tune
And I'm still throwing this code after deactivating the bank 2 o2
My tuner says this code is triggered by exhaust and /or boost leak
Any suggestions???
Thanks guys!!

If you have a boost leak, you run too rich, not too lean. Maybe an exhaust leak? REplace the crush gasket and see if it helps.

Yeah I'm running really richni can smell the gas when I come to a stop. And the code takes a while to come back once it's cleared. I put the new 02 back in by the turbo and it's still throwing cels and there are no leaks anywhere as far as I can tell

more than likely it was a boost leak...every single problem with this car always leads to a leak

Hey guys, I too just got code P2096

I have Dejon charge pipes, ZZP catted DP, GMS1, K&N typhoon , Forged BPV

Is this something serious or minor? I get some rattle in the dash in first gear driving . I don't abuse my car and I am still boosting 21 PSi , so I doubt it is a boost leak. Can anyone help me out here?

Could be a map sensor or a boost leak. OR possibly your intake scewing your fuel trims. The k&N filter can be rotated to help with this a bit. (you will need an Interceptor or some way of monitoring trims though)
