I have an 08 550i and have wanted to get my ECU remap. I was leaning towards the Eurorev after speaking with Vincent but I would have to send my ECU. From what i know about the Eurorev remap, it will provide more HP versus Dinan. However, I am scared that if I have any problems, i would have to send my ecu back to them to flash it whereas my dealership is mod friendly and can provide me a Dinan flash. My only mod is the K&N drop in minus the charcoal filter. Has anyone done the ECU reflash on an 550i with Dinan yet?
