Pulling Turbo Tuner chip before warranty

I'm taking out my intake and Turbo tuner chip before I send my car in for a wastegate rattle investigation (and hopefully turbo replacement).



Are there any tamper codes that will reveal themselves when I remove the chip or while it's in there? Should I unplug the battery prior to removing the chip?



The only thing on my car that will be there that's not stock is the exhaust (RPI quad exhaust). I'm hoping everything pans out okay.
