Getting ready to upgrade to 35's and have been doing some research on programmers. Have to say I am a bit nervous to use one. Have seen a bunch of horror stories about dead jeeps. I did buy a Flashcal but am rethinking using it. Most of the threads are several months old. Anybody got any new info on using this with their '13's. Trying to put my mind at ease.

 

I have a 2013 and have used it with no problems. Changed my tire size and turned off the TPMS because I didn't install TPMS in the new tires.

 

No, issues what so ever. 35s, aev lift

 

Used it on my 09 & now my 13.. Good 2 go!!

 

Those who have used it did you see much of an improvement in throttle response our mpg?

 

I seem to remember the ones having problems we're using the Flaspaq not the Flascal. Flascal only changes minor things like tire and gear sizes, not the engine tune like the more expensive and invasive tuners do. I wouldn't worry about it, I haven't heard of any problems with the Flashcal or the Procal

 

That's kinda what I thought but wasn't 100 % sure. Thanks for the responses.

 

I've used both and didn't have any problems with either one. Currently running with the Flashpaq.
