I'm seriously debating over whether to install the M Power Kit for my 530d XDrive. It costs about US$ 3500.00 here in Korea to do the upgrade and results in the following:

530d AT Series M Performance Power Kit
Acceleration (0-100 km/h) : -0.2 seconds
Power : 258 HP to 286 HP
Torque : 560 Nm (413 lb/ft or 57.2 kg/m) to 600 Nm (443 lb/ft or 61.2 kg/m)

Kit includes:

– New engine control unit including engine data update.
– More powerful charge air cooler.
– BMW M Performance Power Kit aluminium badge
– Brake components for the upgrade on the front axle; 4-piston aluminium fixed calliper, drilled and grooved brake disks, brake pads.
– BMW M Performance sticker for side skirt

Adding this kit retains the factory warranty. Adding a power upgrade kit from another brand may add more HP and torque but voids factory warranty.

Has anyone that's installed the M Power Kit or any other power upgrade modification give some input? Thanks!
