New from Michigan
 

Hello, my name's Kent and I just bought my first diesel today. It's a '95 7.3, automatic. New to diesels and would like to learn all I can about them, it's already chipped and has a 3 inch downpipe into a 4 inch pipe. Mainly looking for fuel economy and performance, in that order. What should I do next? Thanks in advance for the help!

I would do the air intake next,and air filter.:hellox::tu:
