What are the methods to get maximum acceleration from the G20 320i?

[Adv3nture]

This is my first automatic vehicle, and I am uncertain whether I am operating it incorrectly; but, I see that when I accelerate fully, the engine revs to 7000 rpm before shifting up. This seems excessively delayed, since it has exhausted its momentum by 6000, resulting in just noise without tangible benefit. The acceleration seems to be more rapid when I manually shift at about 6000 RPM or when I do not fully depress the accelerator in manual mode.
It features a tuning box that has significantly improved performance; yet, the delayed shifting remains an issue regardless of the box's presence.

What is the mileage of the car?
May be attributable to a box service.
Are there any trouble codes present?

I would assert that it performs like they all do with WOT; indeed, on rare occasions when I apply full throttle, it maintains the gear till the redline.

I first believed this when I acquired my M4, which was mostly used for derivatives. Currently, I rev my M4 to 7,000 RPM, but it is capable of exceeding that by a few hundred RPM.Notably, reaching the maximum RPM in fourth gear will propel me above 130 mph.I consistently utilise paddles or the DTC shifter/gearknob while accelerating.

Additionally, remove that box.

I purchased the vehicle in April of this year from a BMW dealership, which had 13,000 miles on the odometer. I identified the acceleration problem very immediately, attributing it to my unfamiliarity with automatic gearbox and my experience of driving a diesel vehicle for the last decade.
The vehicle has no fault codes; other from this, it is in excellent condition.
Should the automobile exhibit significant tugging at 6000+ RPM, or does the absence of this sensation suggest a malfunction?

[Meltarb]

At 6,000 rpm, you have surpassed the engine's peak torque on the power curve and are approaching maximum rpm, resulting in a decline in performance. It is devoid of any issues.

[Adv3nture]

Understood, but why does the automatic gearbox remain at 7,000 RPM before shifting up?

[Meltarb]

The rationale for the software configuration is unclear; yet, all will comply. A gearbox remap may be beneficial, although, in truth, full throttle is not necessary to get maximum acceleration.

Thank you for the information.
I was concerned that there may be an issue with it.
