Does anyone know what this code is caused by P2096 (post catya;yst fuel trim system too lean bank 1) it started happening after I got my catless dp and my intake both are from dejon. and how do I fix this so it does not happen anymore?

 

you need to tune for the intake. did the dejon dp come with an angled 02 bung?

 

I had it tuned by churches auto they are one of the best and it has the angled 02 bung so I dont know what else to do?
