I have an idea why they won't do it, but they won't say. I talked to a non-DP tuner (won't say who), and they basically told me they won't tune on it. The 0 position is hard to figure out how to get it out if you're not aware how it works (good for anti-theft). I was thinking of getting a Hydra, but the no-start feature is just another position, and frankly I'm not crazy about that. I was thinking of buying a F6 now that it's open source so I could use two different tuners on it and try that route. I tried a TS chip recently (not gonna get into the "who's tunes?" discussion), but really did not like the rotary switch I suppose because I was used to the DP controller.

Now that I have done some performance upgrades, I've gotten tired of pulling my chip out and sending it back. I have had a DP F5 for about 4 years and have come to like the usability of the controller, especially the 0 position no start feature.
