Hey guys, say you are running 91 tune and you need to set it back to 87 tune at the pumps for some reason, is this an easy "on the road" procedure? Or do you have to put some time into it? Also, many of you are talking about using the "tow" tune all the time. Is this a good option for all driving types combined, or if you go on a long highway trip should you change it? I am thinking about one of these flashpacks because I actually hate towing with the jeep with its current power, and the hills in the northeast are driving me crazy when I am not towing,

 

Plug it in and follow the prompts. You'll turn the ignition on/off a few times, so you can't be driving while doing it, but can easily be done 5-10 minutes in a parking spot after you gas up.


Better shift points and 'maybe' better power. No issues running it full time, just depends on how it works for you. Try multiple tunes and decide for yourself.


Don't expect a miracle. It helps, it may be noticeable in the seat of the pants, but it is not insta-hemi power.
