Modifications - Engine Management

Complete engine management systems are available to relive the factory ECU of engine management duties.  Such systems can be very expensive but for high horsepower applications which tax the factory ECU they are a viable alternative to ECU reprogramming.  Furthermore they are completely user tunable.
