I am also wondering how this modification will affect warranty? I would rather choose BMW Performance Engine upgrade before any other, just to keep BMW's warranty. With the BMW M Performance Power Kit for the BMW 320d, you get these numbers, 147 kW, 420 Nm compared to stock 135 kW and 380 Nm. BMW also installs a new control unit and also a larger charge-air cooler. I hope BMW release a Power Kit for the 328i engine.
