I wonder if this true. (Ofc to detach all tunes bfr going in to dealer).

I need real tuner whom have used JB1 and serviced their car under warranty with no problem. Anyone?

Replies much appreciated.
If you just spoke with the people that made the product and they told you no codes will be thrown, what more do you need?

You just spoke with the real tuners. If you are getting an oil change done or whatever else you can leave it installed. Now if you are going in for warranty work I would remove it.
