145: How to Avoid Wasting Thousands on the Dyno

It’s common for car enthusiasts to rush their car onto the dyno before it’s truly ready, only to have it strapped down and the tuner uncover a list of issues. Nothing kills the excitement of chasing those long-awaited power figures faster than unexpected problems.

Shawn shares his journey from a childhood fascination with cars to becoming a self-taught tuner and business owner. He talks about the challenges of diving headfirst into tuning, including his first attempts learning on his FD RX-7. “Piston engines were easy after learning to tune on a Rotary”

We explore how Shawn began his tuning career with Adaptronic before transitioning to Haltech, which he now specializes in and also provides technical support. He outlines his remote tuning process and why it works so effectively, stressing the importance of road-tuning a car before it ever sees the dyno.

Shawn breaks down the pros and cons of remote tuning, including how he manages tricky areas like knock control when the car isn’t physically in front of him. He also touches on CAN bus integration in modern vehicles, an area he’s becoming increasingly involved with.

Spending hours—or even days—on the dyno can quickly add up if things don’t go to plan. Shawn’s focus on minimizing hiccups and maximizing efficiency makes a strong case for his approach. He might just be the one to help get the most out of your car.
