Obviously check into this first as I'm no expert, but if its that big of a deal for u, a couple of hundred bucks is still cheaper than the tire package u would have had to buy before and now u would have no limit.

If you read the MP thread, he clearly states that BMW will know you changed things even though the flash counter is frozen. They can tell based on what the car has done (which is recorded). If you have exceeded 130 and the car is limited, they know you messed with it and risk having warranty denied.
