There seems to be some issues ... Not sure if tune related or (loonie tunes) anvil right foot syndrome  ... And higher Hp and torque numbers facilitating the issues ???  |
In the early part of the release there was some intake related issues with stage 2 being as how BMW saw it fit to have 3 different styles of lower air boxes that changed air flow for all the styles but once those were resolved 95% of the problem cars went away. The stage 1 tune though at this point is about as stable as it can get and shouldn't give any DT malfuction codes at any point. The few that have come up between the various stages on the platform have been rare and isolated and typically not related to the tune. The vast majority of which were actually ultimately a result of marginal fuel pumps (shocker I know) that the dealer troubleshot and replaced. After being replaced the problem never returned.
