Yes, restore. I just took my 2018 for the Cam Phaser recall software update and the guy politely asked me if I took my tune out and restored factory settings. You can't fool them, but good service teams will work with you.
I did the same - but haven't reapplied the tune. I assume any tune changes won't affect whatever base has been changed for the CP rattle? Or did you get a new tune from Cobb.
Also that CP Rattle software update did almost nothing.
