Let's say I have a Dyno done by a professional shop. Now I then get my own handheld device and do a backup. I then make a change, and then at some point reload the origanal back up I saved. Will it still be the same as when I got my original tune from the Dyno or does the hand held device mess up the Dyno settings?
