You would be good to go with a chip. That is what the majority of guys run on the 7.3L. They are easy to install, switch on the fly, and give you multiple different tune choices. We can get you setup with one if you are interested.
If you are looking for something more enhanced with more features, we do offer a programmer called the Infinity. It is a tuner, gauges, diagnostic scan tool, datalogger, and code reader all in one.

Let me know if you have any questions. I'll gladly help you out.
