Hey folks.
when I bought my 2016 435i, I was told it had an MHD stage 2+ tune (not confirmed because I dont know how to check what tune it has and I don't know how accurately the sport display is. It'sgiving me around 400hp and 420 torque on display with 94 octane). I don't have a license key for MHD. Just planning ahead, I was wondering if I wanted to do a different tune in the future, do I need to flash my ecu back to stock before putting a different tune or can I go from one tune to the other. IE bootmod3 or JB4 etc... if I flash it to a different tune, will it give me issues? I have plans to add more performance mods to it next year and I haven't decided what I wanted to do with the tune yet. Just thinking ahead. I'm very new to this.Thanks.

Send your VIN to MHD and they will verify your tune and key. The license key is tied to your VIN so you either have a license and can freely change maps or the previous owner removed the tune before selling and you are stock.
