• Usable torque across the rev range
• Reliability and engine longevity
• Drivability for both daily driving and track use

He often sums up his philosophy as:

“Power you can live with.”

This mindset ensures that his tuned cars feel refined and dependable—not just raw power machines.

Motorsports Career & Major Achievements

Toerwagen Diesel Cup (TDC) Victory

One of Dik’s most significant achievements came in 2011, when he competed in the Toerwagen Diesel Cup (TDC) driving a Volkswagen Golf VI TDI that he personally prepared and tuned.

He didn’t just race—he won. According to Autosport Nederland, Dik claimed a dramatic first race victory during the Profile Tyrecenter Pinksterraces at Circuit Park Zandvoort, starting from 10th position and overtaking rivals in the late stages.

That same season, he was crowned TDC Champion, validating his tuning philosophy under real competitive pressure.

Racing as a Development Lab

For Dik, racing is not merely about trophies—it’s a crucible for engineering. His dual role as tuner and driver gives him a direct feedback loop: what works in a dyno doesn’t always translate on track, and only through endurance, heat cycles, and real-world stress can a tune be truly refined.

Diagnostics, Dyno, and Custom Calibration

JD Engineering’s process reflects Dik’s methodical nature:

1. Full diagnostics and inspection – before making any modifications, every vehicle undergoes a thorough evaluation to ensure mechanical health.
2. In-house dyno testing (4WD) – to measure real-world gains and validate maps under load.
3. Tailored ECU mapping – each tune is custom-made based on the car’s hardware, driving style, and performance goals.
4. Remote tuning capability – for clients who cannot visit Lochem, files can be calibrated based on log data and sent back securely.

Reliability as a Performance Metric

Dik’s engineering ethos strongly values long-term stability:

• He optimizes thermal management (boost, intake temps, exhaust gases) rather than pushing for maximum spike performance.
• He calibrates cold-start behavior, idle stability, and throttle response to closely mimic factory behavior (a philosophy sometimes called “OEM+”).
• His builds are not just for enthusiasts but for those who demand longevity, whether it’s a daily driver or a race car.

Adapting to Modern Times: Hybrid & EV Tuning

As the automotive industry shifts toward electrification, Dik and JD Engineering have started exploring how their expertise applies to new platforms. According to several tuning-industry commentary sources, Dik is investigating software optimizations for torque delivery, battery management, and hybrid drive systems.

This forward-thinking mindset underscores his adaptability—showing that his focus remains not just on legacy combustion engines, but on the evolving future of performance.

Signature Projects & Notable Builds

The Legendary G60 Golf

One of Dik’s earliest and most iconic successes came via the VW Golf 1 16v G60. JD Engineering tuned versions of this car for sprint racing, leveraging the supercharged G60 engine to demonstrate his philosophy.

This build helped cement his reputation among tuning purists: the car was fast, but also reliable and controllable — a reflection of his balanced approach.

The Golf VI TDI Racer

His 2011 TDC-winning Golf VI TDI is perhaps his most famous project. The car wasn’t just a race vehicle; it was a rolling embodiment of his technical philosophy.
