Using language like “stage” can be difficult as the most significant issue is the variation across different types of engines. Stage 1 tuning can look very different from one engine to another, and a Stage 1 car might outperform a Stage 3 vehicle. Ultimately, any modifications or tuning you do to your engine are at your own risk. Generally, the more power you add to an engine, the higher the level of risk. Increasing the power, torque, and performance of the engine puts it under more significant stress, which it may or may not be able to handle. But here at ECU Flash, we ensure our experts take good care of your cars and perform the tuning stages as carefully as possible.
