• How does it work? Here's how it works, BMW X3 G01 M40d engines are made to operate within a wide range of environmental tolerances and to comply with various standards and emission laws allowing sale and use in different countries worldwide. Our device works the same way as a remap and other more expensive eprom chips from Superchips etc. by adjusting the timing curves and optimising your BMW's air/fuel ratio for optimal performance using the modern fuel quality available in your country. The device operates at very low voltages and never exceeds what your BMW X3 G01 M40d engine can handle. It can also be removed at any time in minutes to revert to standard settings, unlike a remap.

• Why so cheap? To keep costs down, we skip the retail packaging. The device is supplied in the basic sealed bag with instructions. We buy in very large quantities direct from the manufacturer, allowing us to pass maximum savings on to our customers.

Choosing this tuning chip over an expensive ECU remap is not only much cheaper, but it's also a safer, more reliable, and completely reversible way to gain power and improve economy. Unlike a permanent remap, our rigorously tested devices are extremely tough, designed to last many years in your vehicle's engine bay, and can be removed or transferred in minutes.
