Technology: The increase of performance gets done through a change of the injection timing and the quantity of injected diesel (or for example at the Common Rail System with the injection pump pressure). The electronic of the Power Box is also connected with the MAF sensor (Air Flow Meter), to guarantee an optimized injection process. The Power Box is installed between the ECU (Electronic Control Unit) and the injection pump. Most of the tuning kits use a standard connection, which can be installed or removed within minutes (not detectable by diagnostics).
