The chips in the drop downs are all for the injectors on the page you are looking at. The Hydra and TS with standard injector tuning is just that. They come tuned for a stock transmission and the injectors on the page.
The custom tunes are from three different companies. Jelibuilt, 1023 Diesel, and Gearhead Automotive. These tunes are custom written for your truck modifications. Most importantly is a built automatic transmission with a modified valve body. These tunes are more refined and utilize the latest tuning techniques.
