Jordan, I'm pretty sure your question was misunderstood. The hardware (which is made by Edge) can support only four tunes (counting your stock tune). Models for diesels hold more.
There's also a competing brand (marketed by XCT I think?) that can hold three custom tunes in addition to three "canned" tunes.
Honestly, though, I anticipate you will find the tune you like, and will drive with it all the time. That's what I do. I only change tunes when I'm towing.
