Oh your question, well I have a modified '04 and I just installed new replacement headers and don't want to blow those out from running too lean and i'm not sure how bad the mpg will be without a programmer anyhow.

So I see you are running the JBA short header? If you still are, a truck running on a stock program should be able to handle them. It's the long tubes that really need tunes. But explain to me more about your custom exhaust and what you did there on that mod so I can understand.
