DP Tuner or TW chip are the favorites around here.

Personally I like TW, but that's because I know him and he lives up the road from me. For you, I'd suggest DP-Tuner. Jody will be up in your area in July and can "live" tune the truck for higher altitudes which might be even better for you. Here's a link to the dates and info on when he'll be there. You can contact TomS for any more info you want. https://www.ford-trucks.com/forums/8...e-19-21-a.html

 

So on the DP tuner you pay one price and then you have to add all the oter 16 position costs? Not sure how this works? I see one price on the tuner and then I saw a price for each position? I do like the high idle, and then maybe 3 or 4 power settings, maybe the exhaust brake option would be nice.

 

Yes- you buy either the F5 for $200 or the F6 for $400 and it comes with no start and stock. Then, you pay for each additional tune you want, usually $45-50.
With the F5 if you do more mods down the road or want more tunes, you have to send the chip back to have it re-burned. With the F6, Jody can email you new tunes and you load them onto the chip yourself- you never have to remove it. You can even test out a new tune for 10 key cycles before you buy it if you wish. I have the F5 and really like it, but if cost weren't an issue I'd go for the F6.
