It is entirely possible to tune a vehicle without having a dynamometer.
While having this tool is preferable for precise results, easier detection of certain anomalies, or safe datalogging, the most important aspect is to verify the work, and this can be done on the road.
It is crucial to conduct a comprehensive diagnostic of the vehicle upon arrival and after performing the modification.
Additionally, it is indispensable to carry out precise datalogging to ensure the proper functioning of the vehicle and the file injected into the engine control unit.
However, we strongly recommend using a dynamometer for Stage 3 tuning to achieve optimal results.
