The engine management system is controlled by an Electronic Control Unit (ECU), which can be reprogrammed to optimize fuel delivery, ignition timing, and boost pressure for maximum power output.

The engine comes with a number of features that contribute to its high-performance capabilities, including forged crankshaft and connecting rods, high-performance pistons, and a high-flow exhaust system. These features allow the engine to handle the increased stresses and pressures that come with high-performance tuning.
