2013 X6 E71 ECU remapping

[Lovelyas]

Greetings everyone, I need counsel.
I just acquired a one-owner 2013 X6 30d Xdrive with only 13,000 miles, which has a complete service history, maintained every 1,000 miles. All documentation is in order.
My concern is that when I accelerate, there is a lack of power for the first few thousand revolutions, after which all the power seems to surge simultaneously.
Is this usual, since this is the first automatic automobile I have owned?
I seem to be using more pressure on the accelerator to maintain turbo engagement, resulting in increased diesel consumption.
may an ECU remap resolve this problem, and if so, which establishments in Northern Ireland may I approach?
Thank you in advance.

Serviced at intervals of every 1000 miles? It likely incurred more expenses in oil than on fuel!😂

In response to your inquiry, no, it will not. You must first address the underlying issue causing the power problem. Any competent mapper will do diagnostics and refrain from mapping a vehicle with an underlying problem.

The next step is to conduct a diagnostic scan using BMW-specific software. Considering the vehicle's age and usage, it has likely been used mostly in urban settings, leading me to predict potential issues such as stuck turbo vanes or a clogged EGR system.

Have the DPF inspected; I suspect the mileage is genuine, since it is rather questionable to me.

I would locate a reputable independent BMW garage and let them to do diagnostics.
All the aforementioned advice is commendable.

I concur with your assertions and initially harboured scepticism; nevertheless, everything corroborated. The service history is documented at a BMW dealership, and the mileage from the service records and MOTs aligns accurately. I also had the vehicle subjected to a professional inspection, including diagnostic assessments, all of which yielded satisfactory results.
Thank you once again for the counsel.

The turbocharger is of a variable type, therefore eliminating the occurrence of a rapid power surge and ensuring a more linear power delivery. My former N57 330d did not display the issues you mention; thus, unless the power delivery in an X model differs owing to BMW mapping, I would assert that there is an issue with the VNT functioning.
