Hello everyone,

I recently installed the Ultimate Performance down/mid pipe kit. After this was done I ended up with the P0038 fault. I installed the non foulers and still came up with the same fault. Do I need a tune to get this fixed? If so, what tune suggestions do you have? Jb4? Lap3 pro tuner? Flash tune? Could this be a bad sensor or the wiring got messed up?

Thanks!
