The acceleration times illustrate the difference in percentages when overtaking before and after BSR tuning.
The acceleration times were timed using a advanced GPS equipment on our airfield. The same gear is used throughout the whole interval so the driver´s skills will not influence the results. (at acceleration from 0-100km/h)
Acceleration is started 10km/h before the time keeping starts, i.e. at the acceleration interval 80-120 km/h the acceleration is started at 70km/h. There are always two people in the vehicle.
The presented acceleration times are mean values calculated from 3 runs in both directions. The acceleration times cannot be compared with other times taken using another vehicle or during different conditions. What you can compare are percentages from other vehicles before and after BSR tunings.

In the cases where only the difference calculated as a percentage is stated the information is from a different car body equipped with the same engine, for instance VW Golf vs Audi A3.

Differences between runs can be:
- Load (such as fuel, sound system, spare wheel, passengers)
- Height of tyres (transmission).
- Wheel rims (oscillating mass)
- Width of tyres (taxiing resistance).
- Vehicle height (air resistance).
- Ground/road (taxiing resistance)
- Angle
- Temperature
- Air pressure
- Humidity
- Fuel quality
- Vehicle condition.
