    2014 BMW 535i xDrive Preformance upgrade

    Hello everyone,

    I'm a new member in this forum.

    I have a 2014 535i xDrive (F10-N55 engine) and it's my daily driver and I don't want to have issues and check engine lights.
    I currently have dinantronics stage 1 chip on it and M Preformance exhaust.

    I want to reach 400 or 450 hp.
    What do you guys recommend?
    I was thinking an air intake+catless downpipe + charge pipe and maybe an intercooler if needed.
    Dinan doesn't have stage 2 tune so I think I have to go with JB4 unless you have a better recommendation.
    I'm kinda new to the performance tuning stuff.
    Please list companies and parts that you recommend.

    Hope to hear your opinions.

    400-450hp isn't possible with the stock turbocharger, period. It cannot flow a large enough volume to attain that, even with all the bolt on supporting mods about 375hp is all you're going to see out of it.

    The stock BOSCH HPFP isn't going to flow enough fuel to support power output in excess of 400hp either.

    You're going to have to upgrade the turbocharger, fuel system and get real with the performance software (Not Dinan) I'd recommend checking out Mission Performance. With flash tuning now available JB4's are dead IMO.

    Charge pipe is a requisite to doing anything to raise the boost pressure levels, its known to burst under stock boost and I've replaced dozens of them on completely stock cars.
