+ for stage3motorsports.
Just got there tuner for my 2014 Eco fx4 happy with the tunes. Also they are very quick to respond to any questions or concerns you have.

 

I'll second the above. Just order from Stage3, great response times to questions and get things rolling quickly. Should be getting mine soon in the mail.

 

Thank you guys! As far as the data logging question...

Depends what you are having issues with. So if you are having an issue with a WOT we would need a data log during the issue. Hope that makes sense.

 

another + for stage 3 and 5*. Got my order from them installed over the weekend. Truck is doing great. And I feel good with the warranty I got with it.

 

Can these tuners also reprogram for tire size?

 

The tuner can reprogram but also has the option to leave revolutions per mile open for the end user to put a value in. The question is for stage3 does 5* leave it where a user can enter a value?

 

No, we lock it on our warranty tunes because we will not warranty 36 inch and above tire tunes. Tunes sent that are not warrantied we leave it open. We will change tire size for you for free on the warranty tunes.

 

Thank you and thank you for your reviews on our site.

 

So the problem here is that in the past 5* could never get my speedo where I wanted it and 5* told me he got it as close as he could and wouldn't keep trying. MPT, LET, and others left it open and it is dead on with GPS. Is that correct? Idk but it's what I wanted.

Maybe dealing with Stage3 would be easier....

 

I just edited my post, here is the new version
