Ever wondered exactly what an ECU remap delivers on popular marques?
We’ve flashed a range of BMW, Audi, VW and Ford models on our rolling road and on the road—so you see the gains before you book.
No guesswork, just real dyno sheets and road-test feedback.
Why Brand-Specific Data Matters
Each engine reacts differently to revised boost, fuel and ignition settings.
A 2.0-litre diesel BMW responds in one way, while a 1.5-litre VW petrol behaves another.
By sharing model-by-model results, you know what to expect whether you drive an M Performance car or a family hatchback.
