We dig into the efficiency of diesel engines and discuss some of the biggest myths in the diesel world, including the pros and cons of modern emissions control systems and how they really impact performance. The conversation also dives into diesel tuning—what sets diesel apart from gasoline, why exhaust gas temperature (EGT) matters, and how it plays a critical role in monitoring engine performance. Of course, we couldn’t resist weighing in on the long-standing debate between Powerstroke, Cummins, and Duramax.
