You will need to remove the Hydra/6pos chip from the PCM to upload new tunes where as the programmer stores in a console or glovebox and is ready to be modified in real time.Ī major benefit for me applies to the work applications and large fluctuations in payload my truck experiences. A big difference being ease of tune uploads to the SCT Programmer. You can also be emailed alternative tunes, and is a press button, switch on the fly option. I will always recommend it as it remains a simple, reliable, and user friendly solution for custom tuning. Comparably, The Hydra w/Flash gives you 15 spaces (or more now?) for custom tunes and is an awesome solution as well. This opens up the availability of selecting a limitless combination of tunes and tuners available to you and the truck in seconds.

Most of the tuners mentioned above can email you their custom tunes, you upload them onto the SCT Programmer. Are you interested in the option to switch tunes on the fly? Or does that matter to you? I run the SCT Programmer ( previously Hydra) with 10 custom tune slots as well as the three pre-loaded tunes supplied.
