In today's world the most important tools for tuning are no longer found in your toolbox. Just think, in the 1980's Top Fuel dragsters made 2500 hp using a 500 cubic inch ( 8.2 Liter) Aluminum Hemi headed engine, as amazing as this might sound, today this same displacement and very similar looking hemi headed engines are making over 8000 hp! Why? It is all about optimizing all aspects of the engine to improving efficiency. This demands the tools to gather data so you can understand what is happening inside the engine and identify opportunities to improve efficiency.
