Short Answer: Yes

"Long Answer: No. Your tune will come undetectable and you can reflash to the stock tune before sending it to the shop. No ECU rewrites are recorded with this tune. Even with the tune enabled, most dealerships won't notice a change unless they drive it in semi-manual mode (AKA now sport mode), if they put it in drive it will actually be a little less powerful than stock to gain nice MPG (Eco-mode).

*I am not an expert, but this is my understanding from following this thread and others."

Above was a conversation that was had in the latest Trifecta Group buy.
