Gas mileage gone I don't know whats going on. My mileage has gone down from 330 miles a tank to 260! Could it be my O2 sensors, or do I need to be tuned as well?

Well the Y pipe bolts up to the header flange, and then I have a bullet put onto the other end of the Y with support of a band clamp, but everything is solid. I've had this setup since Jan. '06 and only recently having mileage issues.

I just put LT's on my car and my gas mileage sucks now too. I must really need a tune. Will a predator fix this? Or should I just suck it up and pay for the tune?
