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. If not, you aren't out much.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. So if you like it, pay for it and Jody gives you the unlock codes. IOW, you download the tune you have 10 ignition cycles before it locks out. With the F6 I would be able to download the tunes and do a 'try before you buy'.

Also I put a piece of sponge between the tape and chip so the sticky stuff doesn't contact the chip. To R&R it, I have to unhitch the harness, take it out, cut the tape and remove. It takes me a while to R&R it since I tape the chip down. Also with the F6, you can download tunes WITHOUT taking it out. I prefer the DP chip because it is more technologically advanced than the old obsolete rotary dial stuff. So, while the TS chip, you have choices, what real choice do you have? Do you want KFC on 4th, 5th or 6th Street? Might be slight difference but not much real difference.

They took a truck with a set number of mods and let the tuners go wild then put the truck with the tune on the dyno. IOW, there was no one tuner that was head and shoulders above the rest. While it is true that going with DP means you have to use their tunes, they did a test a month ago in a diesel mag and there wasn't that much of a difference between the tuners.
