im in the same boat, and have recently got a 320d. BMW performance tune - they change the torque converter in the auto box, and install a 600w fan. Is it worth getting a tune from an external company and taking the risk?, also most of them tune to 440nm of tq and the 320d gearbox is rated to 400nm. I have sent an email to superchips asking if they can do a custom tune that does not exceed the gearbox limits, hope to get a reply soon. have tried finding an uprated gearbox torque converter with no luck
