Installed headers and Supercharger with mail order tune on A4. The car is running super rich. Its chugs and idles rough unless im in the gas.
Its running codes PO132C, PO300H which is O2s. Tried putting new o2 in both sides and nothing same codes. Put scanner on and it read around 960mv on bank 1 sensor one. So right now I pulled fuse to run open loop. Can the o2s be crossed or what, NEED HELP.

Also running TCS1286HC and HVAC BO333HC are they because of the o2s.

Do you think it is more in the tune or something I did?????!!!!!????!!

960mv means you are rich[132=o2 voltage high]300 is random misfires,probably because you are rich.pulling the fuse will make bank 2 rich[o2 will run cold],bank 1 fuel trims should be on the minus[-]side with running that fat.pull the plugs on 1.if they are all black,you have too much fuel.if the plugs don't look that bad,either you have a wiring problem or a bad o2 [most likely if you have a lot of miles].swap front o2's,if the fault goes to bank 2 ,your issue is a dead o2.
