I think the MyKey can reduce performance for valets or teen drivers. It could be that it was always programmed (used vehicle?) and you just switched keys. each key can be programmed differently.

my truck is a 5.0, and either ive gotten used to the awesome power and pull, or it seems a lil doggie compared to when I first got it? Don't get me wrong, it runs good, but...? I might try this battery thing, will I lose anything more than the radio presets? Like my android auto, comfort settings, etc..., stuff like that? Thanx, curious.

Everything on this truck is learning and adaptive... trans, throttle, etc. Pull the battery cables and touch them for about 10 minutes as stated above. This clears all canbus memory and most of the electrical static from the system. Put them back together and go drive the 
out of it. It will relearn all the goodies.

Yes remove both. Touch both leads together with a piece of wire, without any connection to the battery. I use a test lead that has a clip on both ends, so you dont have to hold it there.
