What companies offer a re-flash in case BMW Service brings a cars tune back to stock?
How is that safer? Dinan will warranty your engine if something happens as a result of their parts, but the dealership will not. You'll end up in essentially the same place as the OP, since the dealer is just as likely to void your warranty with Dinan as they are with Powerchip or any other brand.
