Exergy Performance is a division of Exergy Engineering and is focused on the unique needs of high-performance diesel applications. The need for this specialized attention was recognized after assisting in root cause analysis of everything from rough idle to broken engine components caused by well-meaning, but inexperienced and/or under-equipped fuel system modifiers. Given our history in the world of diesel fuel injection, we have a distinct advantage in the areas of experience, innovation, and test equipment. With our background in OE development and manufacturing, we bring a unique perspective to the high-performance world. We know what various features and specifications need to be to ensure proper function, how to produce them, and how to verify they are correct. The verification process/equipment we use is very untypical of a standard diesel repair shop and allows us to look at many more system performance characteristics beyond average fuel output.
