Chiptuning, BMW Exx N55
With an ECU remap, also known as “chip tuning” or “reflash”, the original ECU of the car will be recalibrated on several different engine parameters for more performance. Options like speed limiter removal and start/stop deactivation are available. Please note that an ECU remap will void the factory warranty once detected by a BMW dealer. Installation and back to stock can be done by an official Mosselman Dealer.
The ECU Remap will take your BMW X5 35i E70 306hp to approximately 356 hp and 510 Nm on premium fuel (98 Oct EU / 93 Oct USA), which is highly recommended.
