The injection pressure is an important parameter in chiptuning. The injection pressure results from the injection quantity and injection time. The CPA technicians access the values of the injection pressure in order to change the values via the individual software of the CPA PowerBox so that the power reserves of the engine can be used. Each engine requires individual settings and needs therefore be precisely adapted and tested. The CPA technical team records the values of the respective car and adapts the in-house software individually in order to achieve more driving pleasure without negatively affecting the service life of the engine.
