I've heard from BMW owners that have had the reflash done, that the car's feel slower than before. I'm still not sure if I want to have this done. The fuel pump was just replaced in January but I don't think they reflashed the computer.
I thought about the Dinan but it's a total pain to have it reflashed every time it needs service ot warranty. That's what made me decide on the Cobb.

With a tuned car those software updates that may or may not make your car "feel" slower wont really matter. Just plug the cobb in and enjoy the ride!
