Swapping out tuned PCM for stock?

[WILLFG]

I have a tuned PCM in my 05 Yukon right now but I also have a stock one.

If I wanted to just swap in the stock one is there anything else I have to do?

Or could I just unplug the tuned one and plug in the stock one and be good to go?

Thanks

Security relearn will need to be performed.

it will also have to re learn all your driving habits so it mite shift a little funny at first

What's a "security relearn". I've been tinkering with tuning for quite some time and never heard of this. Care to elaborate?

Security relearn is the initial proceedure to bypass the security system when you swap out PCMs.
