Golf IV TDI 110PS: What's the value?

Highline trim level + climate control.
'Unladen weight: 1313 kg + accessories (I estimate the air conditioning system adds about 30 kg), tire size: 205/55-16.'
The Ulfscher permeability test yielded the following approximate results:
All tests were conducted using biodiesel .

2000 - 4000 revolutions per minute, 3rd gear, original condition approximately 9 seconds .

2000 - 4000 revolutions per minute, 3rd gear, with Speedbuster box , approximately 8 seconds , sometimes a little more or less.

I'm not entirely sure if the settings on the control unit are optimal (I adjusted them myself). Do you have similar values for the same vehicle model?
The maximum speed, 200 km/h , according to the speedometer with the box, has a rotational speed of 4400 revolutions.
Thank you for the answers}}.

I also have a Highline G IV with Climatronic and 215/45 R17 tires all around.
However, the Ulftest showed better results:

2000-4000 rpm in 8.3 seconds.

with a 10-cent tuning.

2000-4000 rpm, 6.8 seconds.

(all values are averages, and each measurement was performed multiple times).

Hi!

A3 with chip: 2,000 to 4,000 RPM, 5.3 seconds. In freezing winter temperatures, even 4.7 seconds (honestly, at least 20 measurements). Unfortunately, I don't have any data without the chip.

Best regards,
Uwe.

Hi.

According to the DZR (German Road Traffic Regulations), your car, weighing 1350 kg and with normal engine performance, should theoretically accelerate from 2000 to 4000 rpm in approximately 7.7 seconds.

An estimated 5% power loss due to biodiesel results in approximately 8.2 seconds.

A 2% incline, a 40 km/h headwind, an extra 150 kilograms of weight, or a further 8% loss of power (or a combination of these factors) will extend the time to approximately 9 seconds.

You must determine for yourself which of these statements are true.

If the engine is not performing as expected, it is recommended to check or replace the diesel filter, as these tend to clog more easily when using biodiesel compared to regular diesel.

The maximum speed is acceptable with the box and biodiesel. If it's "real," meaning measured on a flat surface with no wind, the slightly sluggish acceleration is probably not due to a lack of power.

The torque loss with biodiesel is enormous. Based on my subjective estimate, it's significantly more than 10%. I've driven with it myself. The maximum speed was fine, but the torque was significantly reduced.
