    The biggest draw back would be voiding an engine or drivetrain warranty.
    My current thinking is that although BMW can't interrogate the ECU to see any changes, they will record boost levels and speed with fault codes, or possibly even just log the maximum values which gives the game away.

    With or without logging, there's a big change on diesels, you'd want to see a decent return on your money, and anyone who knows the cars well enough would also notice the difference if they took it for a test drive.

    There will be increased wear and strain on components, but there aren't any standard figures where you could compare when an stock car's parts would wear out compared to a modified one.
    Anything you can find on a modified car that has worn out, you'd be able to find on a stock car with lower miles.


    There's a greater difference between different drivers than tuned vs original.

    The greatest example is probably turbos, having a cool down period on a turbo before shutting them off can make them pretty much last forever, but shutting off a hot engine with a fast spinning turbo can have far greater effects.

    I believe the small turbo on the x35d's is a common point where the vanes gunk up and fail to move.


    The pros are more fun, power, and usually an mpg increase of 2-4mpg for normal driving.

    Nice open and honest feedback there from an engine tuner (the horses mouth if you will ).

    To be commended

    I remapped my 335d 6 months ago & so far no cons.The only thing is the gear box works a little harder in Auto mode.The power is fantastic & Mpg is up.Mine is sitting at 350bhp & 700nm.You can go higher but trust me that is enough.Remember rear tyres are expensive.I would recommend remapping your car it is fun !

    you have the expert's feedback aka The End, so from a non-expert would a downside be that (assuming you tell them) you're insurance premium would rise?

    Yes, there will be changes, and you may need to find out before if modifications are allowed.

    A lot of the insurance companies are still completely behind the times, with different rates for "chipped" and "remapped" which have no effective differences between each other.
