2012 BMW X6 40d E71

[FrostyTomato]

I have just transitioned from a 430d F32 to an X6 40d E71, and I must admit that after a few days, I find myself quite disappointed. I understand they are fundamentally different vehicles, but I anticipated more speed. Would a remap and DPF removal enhance its performance? Perhaps we might consider the removal of the EGR valve and swirl flaps together.

It is premature to proceed with the remap; diagnostics must be conducted to ensure the system's health, since a vacuum problem may be impairing turbo functionality.

I would not consider removing the DPF; some years ago it may have been feasible, but current regulations are stringent, making it not worth the inconvenience.

There may be an issue; nevertheless, the sensation of speed between cars will likely be minimal. The X6 has four-wheel drive, which may affect its initial acceleration. As previously said, a thorough diagnostic is necessary. No competent remapper would undertake a remap without doing a comprehensive BMW software problem diagnosis.
