folks, considering having dinan stage 3 tune installed on my f10 2012 550i xdrive (n63 engine) but would value any long term feedback of people who have (had) the tune installed before pulling the trigger; in particular, interested in car reliability vs stock, as not keen to see any drivetrain malfunction or error message of that type. i have a full (cat back) m5 exhaust on my car, otherwise no mod. i had stage 1 bms before, worked well but would now want more kick and full ECU flash instead of piggy back (i.e., for good or bad not interested in jb4).

by advance many thanks for your feedback!
