If you own a Golf, Audi, Cupra, or Porsche and you’re scared of tuning because you’ve heard too many horror stories about melted pistons, you’re in the right place. I’m going to tell you about a 56-year-old Dutch guy who races, proved his ideas work, and still answers the phone himself when you have questions.
3 Things You’ll Learn Today

- How his “balanced” tunes actually save you money on fuel
- What real customers say after 50,000+ km with a Jeroen Dik map
Who Is Jeroen Dik?
Imagine a quiet town in the north of the Netherlands. That’s Wolvega, where Jeroen Dik was born on 13 March 1969. Cars were his obsession from day one. While other kids were playing football, he was tearing apart anything with an engine.
From Racetrack to Tuning Legend
In 2010, Jeroen Dik entered the Toerwagen Diesel Cup with a VW Golf VI TDI that most people laughed at – until he finished second overall and grabbed six race wins. In 2011, he came back and took the championship. Same diesel engine, no wild modifications, just perfect tuning.
Born 1969 – Age 56, Still Behind the Dyno
Walk into JD Engineering today, and you’ll probably find Jeroen Dik with a coffee in one hand and a laptop in the other, checking log files from customers all over Europe.

That trophy still sits on the shelf at the workshop – a daily reminder that finishing a season with the same engine you started with matters more than any peak power figure.
What Makes Jeroen Dik’s Tuning Different
Most tuners want to show you the biggest graph. Jeroen wants to show you the smallest repair bill five years from now.
The “Balanced Tuning” Philosophy Explained
He looks at boost, ignition timing, and fuel delivery, and asks one question: “Will this still be happy at 200,000 km?” If the answer is maybe, he turns the knobs down.
Reliability First: Why He Rejects 500+ HP Claims
You’ll see companies bragging about 500 hp Golf Rs. Jeroen says, “Great for Instagram, terrible for traffic lights in the rain and your gearbox in two years.”

He took a bone-stock 2.0 TDI to six victories against modified cars. That proved the philosophy works when every single race finish matters.
JD Engineering Services in 2025
The workshop in Wolvega looks more like a lab than a regular garage. Clean floors, rolling road, and shelves full of ECUs waiting to go home happier.
- ECU Remapping (Stage 1–3) for EA888 & EA855 engines
- Simos19 Tuning – one of the first safe solutions in Europe (new Golf 8 R, Audi S3 8Y, Cupra Leon)
- DSG gearbox software for faster, smoother shifts
- Hybrid & mild-hybrid packages that keep the electric side happy
- Custom dyno sessions with full data logging
Before & After: Real Customer Results
Let me show you four normal cars that people actually drive every day.
- 2023 Golf 8 GTI Stock: 265 hp → Jeroen Dik Stage 1: 330 hp / 480 Nm Owner after 45,000 km: “Still averaging 7.2 l/100 km, zero problems.”
- 2024 Audi S3 8Y (Simos19) Stock: 310 hp → After: 390 hp / 530 Nm “No more flat spot at 3000 rpm, shifts as it should have from the factory.”
- Cupra Formentor VZ 2.0 TSI Stock: 310 hp → Stage 1 + DSG: 380 hp / 510 Nm “My wife didn’t even notice until I showed her the graph – that’s how smooth it is.”
- Porsche Macan 2.0 (client from Belgium) Stock: 252 hp → After: 320 hp / 460 Nm “Finally feels like a proper Porsche.”
Jeroen Dik vs Other Tuning Companies
Here’s a quick, honest comparison people actually care about:
- Jeroen Dik & JD Engineering– safe maps, easy to revert, personal support
- APR / Revo / Unitronic – more power on paper, sometimes harsher drivability
- Cheap eBay / Facebook tunes – big numbers, big risk, no one to call when it goes wrong
If you just want the biggest number to show your mates, JD probably isn’t for you. If you want to enjoy the car for the next ten years, it is.
How Much Does JD Engineering Tuning Cost?
No secrets here – prices in 2025:
- Stage 1 ECU remap only: €549–€799 (depends on model)
- Stage 1 + DSG tune package: €899–€1,199
- Full hardware + Stage 2: €2,000–€3,500
- Dyno time: €120–€160 per hour
Yes, it’s more than a €299 file from the internet. You’re paying for someone who will still help you three years later.
Common Pain Points & JD Solutions
I read the forums so you don’t have to. These are the worries I see every week. Warranty panic? They can flash the car back to 100% stock in ten minutes and the dealer never knows. Live in Spain, Germany, UK? Send your ECU by insured courier. Most customers get it back in under a week. “But I want more than Stage 1!” No problem – Jeroen offers Stage 2 and track packages, but only after he’s sure your hardware can live with it.
Future of Tuning According to Jeroen Dik
He’s already working on hybrid Golf GTE and Cupra Formentor files that keep the factory battery warranty. The new dyno room will run on solar panels next year. The guy who won races in a diesel is now getting ready for the electric age – same careful mindset.
Final Verdict
Jeroen Dik isn’t just another tuner with a dyno graph — he’s a racer who proved that power means nothing without reliability. His balanced tuning philosophy, real-world race wins, and thousands of long-term happy customers make JD Engineering one of Europe’s safest choices for ECU and DSG upgrades. If you want your VAG car to be quicker, smoother, and still trouble-free years later, Jeroen’s approach is the one you can trust.
FAQs
1. Is JD Engineering tuning safe for daily-driven cars?
Yes. Jeroen’s entire tuning philosophy revolves around long-term reliability. His maps stay within factory safety limits for boost, timing, and fuel, ensuring your car runs safely for 100,000–200,000+ km. Most customers report zero issues even after years.
2. Will tuning void my dealership warranty?
Technically, any remap can be detectable, but JD Engineering can flash your car back to 100% stock in minutes. Many customers visit dealerships for service without any warnings or flags. It’s not a guarantee, but JD minimizes the risk better than most tuners.
3. How much power can I expect from a JD Engineering Stage 1?
It depends on the model, but most EA888/TSI engines gain 50–80 hp and 100–150 Nm while maintaining stock-like smoothness. On Simos19 cars (Golf 8 R, Audi S3 8Y), gains are even stronger thanks to their advanced ECU.
4. Do JD Engineering tunes affect fuel economy?
Surprisingly, fuel economy often stays the same—or gets slightly better. Because the engine works more efficiently and you don’t need to push as hard for acceleration, many owners report 0.2–0.5 L/100 km improvements in daily driving.
5. Can I send my ECU if I live outside the Netherlands?
Yes. JD Engineering works with customers across Europe. You can ship your ECU via insured courier, and most customers get it back within a week. They also offer clear instructions and support throughout the process.
