Im looking into picking up a 335is with the N54, I am not sure if it has a custom tune on it, dealer says its stock but just to be sure id like to flash it back to the stock tune as soon as I get it. Just have a couple questions regarding the technicality of it.

So first, as far as I understand MHD will source a stock tune directly from BMW based off my DME's ROM code? (KM0S vs IJE0S vs I80AS).

Can anyone confirm that;
1. The stock tune is sourced from BMW and is what BMW would flash on a 335is and NOT an OTS tune desinged to mimic stock boost tables and operation

2. That it removes all traces of MHD when I flash it back to stock

3. Is my understanding correct with how MHD gets the stock tune file for the vehicle? My fear is that MHD will flash a 335i stock tune when its supposed to be a 335is, or that its not a genuine BMW file and its an OTS tune desinged to mimic a BMW genuine tune.
