    Default

    Order a new PCM from a performance shop, I used Nelson Performance , give these guys a call. You'll need an o2 delete, and cat delete. It's 200 bucks...but free updates for as long as you own the vehicle, so if you change anything else, you just pay shipping and they'll flash you a new pcm for whatever modifications may come.

    Or you can run o2 sims.
