Pro, if you do however decide not to change it back to stock, I would tell them if I were you. I've heard stories of guys with custom tunes not mentioning anything to the dealer, and then the car goes in for service, and they do something to the pcm not knowing there is an after market tune, and **** gets all fubared. I don't know how much truth is behind these stories, but better safe than sorry. Either pull the tune, or tell them about it. If your service manager is a dick, you're probably best to just pull the tune for all the time it takes.
