What's intereting is you keep saying its not an issue but it is, no idea how are you're passing with mismatch engine control unit or your county is not really checking for that?

I'm confused..
He is talking about 2 things. In short, flashing to STOCK AND RELOCKING puts stock untampered flash on the car and its CVN/CALID match on the DME. Period, full stop, end of story.
