In this episode of Tuned In, Jamin shares his journey from a kid who loved tinkering to becoming an engineer and respected automotive YouTuber. We also explore how he balances a full-time career in nuclear power with content creation, fueled by his passion for making complex automotive concepts easy to understand.

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.

If you haven’t checked out Jamin’s YouTube channel yet, do yourself a favour and head over there. Fair warning: you might lose track of time—but at least you’ll come away knowing a whole lot more than when you started.
