Hi Bob,

The dealership can reflash the Upsolute program back to factory program. We will reflash it back to Upsolute for free if it ever happens. That is why Upsolute chips are undetectable by the dealerships with their diagnostic tools, because they can be reflashed and we use all factory chips for reflashing.

We are located in Toronto and the groupbuy pricing will only be valid through us. You can always ship your ECU to us. We provide free next day return shipping as well.

Gary
