To chip or program?
 

I have driven diesels all of my life and owned a corn binder i recently purchased a 96 F-250 4X4 looking for a little more out of it what are some proven parts? It came with an up graded air filter any other necessary parts for longevity?

stright pipe it and do the down pipe you will notice a difference in power and fuel mileage.
