I'm interested in ordering a tuner for my 05 5.7 grand Cherokee how do I get it preloaded with a custom tune I have a straight piped exhaust I'm looking for a little more than a out of the box tune what info will I need to provide to get a tune that is for my spec

you'll obtain custom tuning through a cmr tuner like hemifevertuning.com, or Jay Greene, etc.


Thanks
