Sure they can tell...that's not just with the new ones. That's been from day one of the OBDIIs.
It's just like your desktop computer that you are staring into right now...it stores information and it keeps footprints. It's like that porn site that you went to a while back (yep...don't deny it) and peered around for a little while. When you left it you traced your footsteps and erased your history, cleared the cookies, and pretty much everything you could think of doing. Well, if your wife knew how and wanted to, she could still go in there and see where you've been. It leaves a footprint on that computer forever. The same thing with the trucks computer. They can tell off on you.
BUT, for the dealership to do that...they've got to go into the truck and take the computer out and send it off to someone that knows what they're doing. The chances of that happening is pretty slim because they don't want to take the time to do it nor do they want your truck taking up space on their lot. They will look at you and ask you if you've had anything on the truck. Your reply, "No.". Then they may say that their computer says the boost pressure history readings are a little higher than normal and the fuel pressure history readings are higher as well. Your response. "Ok. That's why I've brought it to you. Something is wrong somewhere.".
It's actually quite simple. Of course, I'd NEVER tell you to do this though. This is just hypothetically speaking.
