A Bully Dog tune would be a Godsend. Point bank. I bought DT LT headers through TRD sparks, had them installed, and have had issues ever since, still have the first stage cats and all sensors in place. Unichip says its not their programming. Dealer won't touch it. Talking to Micah at TRD sparks over the past few months, he said a BD tune would negate a lot of the FFV problems folks have been having. I'd guinea pig my truck out and pay for it just so I can get it working properly again. Hope this product comes out.
