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. No idea.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. Might take a look at it tomorrow and see if it was possible he might have bumped the chip and it moved on the PCM or what. Kinda interesting though it happend on the same day, with a new DP tune installed. I guess he pulled over to the side of the road, and pulled the chip out, and restarted the truck. Every light that could pretty much come on came on, and the truck lost all power. He said if you looked at his gauge cluster. But called this morning wondering what was going on. Just made sure the key was out of the ignition. You are supposed to just take the silicone off, if you go to the copper youve acually gone to far. The PCM was already cleaned of the silicone. His truck already had a chip from the previous owner. He sent it out, got the same tunes i had burnt for his 2000. I recently got rid of my perfectly fine DP.
