Joe Simpson didn’t grow up building cars with his dad or surrounded by race engines. Instead, an early fascination with imports, turbo Hondas, and the underground tuning scene slowly pulled him towards a career he never originally planned—eventually becoming an incredible fabricator and tuner.

In this episode of Tuned In, Joe explains how he started with almost no mechanical experience before teaching himself fabrication and tuning out of necessity. Beginning with basic piggyback controllers and early Hondata systems, he steadily built his skills through repetition, experimentation, and plenty of time on the dyno.

We also explore Joe’s transition from Honda tuning into domestic performance, HP Tuners, and eventually the Holley EFI ecosystem. He breaks down the differences between the Sniper, Terminator X, HP, and Dominator systems, where each works best, and why the most expensive ECU is not automatically the right solution.

Joe and Andre also discuss why making huge horsepower numbers can be easier than achieving factory-like street manners. Cold starts, idle control, drivability, and reliable power management can require far more attention than simply producing an impressive dyno result. Finally, Joe shares how his YouTube channel evolved into Tune The Trilogy, turning years of workshop and tuning experience into online education.

This conversation is full of practical insights and real-world experience. Joe’s honest approach to learning, problem-solving, and continuous improvement makes this an episode every performance enthusiast can take something away from.

In this episode of Tuned In, Martin shares how growing up around machinery and studying mechanical engineering laid the foundations for his career. After working in his father’s machine shop, he discovered a passion for designing and manufacturing performance parts that solved real problems, eventually helping shape AMS into one of the world's most respected performance companies.

We follow AMS’s evolution from Mitsubishi Evos to the R35 GT-R, where relentless testing pushed the team to develop stronger engines, turbo systems, and drivetrain solutions. Martin explains how repeated failures lead to innovations, proving that successful product development is built on continuous refinement.

The conversation also explores AMS’s move into the Audi R8 and Lamborghini Huracán platforms, the challenges of modern ECUs and dual-clutch transmissions, and why the biggest dyno number doesn't always make the best street car. Martin also shares the realities of growing a specialist workshop into a global engineering and manufacturing business.

This episode is packed with insight into engine development, product design, and building a successful performance business. Whether you're chasing horsepower or creating better parts, Martin's experience shows that the best results come from understanding the engineering and never stopping the development process.

We often hear about drivers who built successful racing careers, but Peter Farrell’s story goes far beyond the driver’s seat. While many enthusiasts know him for his work developing the legendary Mazda FD RX-7, his career stretches from rallying on a shoestring budget in New Zealand to developing some of the first performance upgrades for the FD and competing in factory-backed racing programs in the United States.

After discovering rallying as a teenager, Peter combined his engineering background with an obsession for making cars faster. Whether it was pioneering turbocharged Ford Escorts, competing against legends like Possum Bourne, or moving to America with little more than ambition and mechanical skill, every chapter of his story was built on finding opportunities and making the most of them.

That determination eventually led Peter into professional endurance racing, where he drove for manufacturers including Mitsubishi, Peugeot, Saturn, and most famously Mazda. Along the way he helped develop the FD RX-7 into a race-winning platform, worked alongside Mazda's engineers in Japan, pioneered performance parts for the iconic rotary sports car, and experienced the golden era of factory-backed motorsport in America.

Beyond the racing, Peter shares invaluable insights into engine development, turbocharging, cooling, reliability, and why understanding the fundamentals matters just as much as having the latest technology. His stories highlight how ingenuity, persistence, and strong relationships opened doors that money alone never could.

This episode is packed with incredible stories from a fascinating motorsport career. From grassroots rallying and endurance racing to rotary development and factory engineering, Peter's journey offers lessons that every racer, tuner, and enthusiast can appreciate.
