Want to know what power your car is really making? Our performance dyno testing service

and diagnostics. Whether you’re looking to benchmark before tuning or verify results after
upgrades, we provide reliable power runs for all VW Group vehicles.
What is dyno testing?
A dyno test helps identify issues like power loss, underboost, or incorrect fuelling, and is also
used to verify performance after a remap or hardware upgrade. At VGS, we use this data to give
you a real picture of how your VW, Audi, Skoda or Cupra is running — no guesswork, no inflated
numbers.
Dyno testing is the process of measuring your car’s power output using a controlled set of
rollers, often referred to as a rolling road. It calculates brake horsepower (bhp), torque, and
other engine metrics across the rev range, showing exactly how your car performs under load.
What we offer
We run a Hub Dyno setup at our Swindon workshop, suitable for both 2WD and Haldex 4WD
vehicles. All runs include cooling fans, data logging and post-run analysis.
