[@Mburn17]

Brilliant video again, wish I did this on mine first. Maybe on the next car

[@Junaid1ahmed786]

Well done bro your smashing it 👊🏼👊🏼👊🏼👊🏼

[@donperryautomotive]

One of the least rewarding upgrades I've done on this car. IF you not racing your car you don't need it.

[@cjmoritz]

will the tune void the warranty?

[@carcodesecure]

Yes, any flashing of the ECU/TCU will technically void warranty.

[@rakiable]

Would it have similar advantages on 520d?

[@carcodesecure]

Definitely. Any f series or g series with compatible transmission will benefit.
