ECO Tuning As Standard

There's no need for two different sets of software to get fuel economy gains or for performance gains. Most maps within the ECU software are three dimensional and can be optimised at different load ranges. With our advanced software upgrades you won't only get great power gains, you can also save some fuel thanks to small optimisations made to injection timing, fuel pressure at part load, torque delivery at the low end and even turbo VNT adjustments.

Check out our excellent reviews!

After 10+ years of working with HDI engines we know them better than anyone. All remaps are the result of months or even years of research, testing, and development upon the engine they are applied to. This ensures the best possible performance and driveability from our remaps.

This is the ONLY place you should go to if you are looking to tune HDi engines.Steven is amazing, he was always available for any question I had and always was glad to help.I did the TD02 Swap to GTD1244VZ and got an entirely different car back! This tune feels like OEM but with CRAZY amount of torque and power.Will definitely recommend to everybody.Look no else than HDi tuning!Big thanks to Steven and his team, really really great people.

HDI Tuning did an amazing job with my car. I got a Stage 1 tune with EGR, DPF, MAF, and doser delete, and the results were incredible. Before this, I had my car mapped by someone else, and it was a mess—constantly throwing engine codes and running poorly. But after HDI Tuning worked their magic, the transformation was unbelievable. The car now has much more power, no fault codes, and runs perfectly.Stephen from HDI Tuning went above and beyond. He helped me diagnose an overboosting issue that no local mechanic could figure out. Stephen's expertise and dedication made all the difference, and thanks to him, I was able to quickly fix the problem.The customer service was top-notch from start to finish. Stephen was patient, knowledgeable, and genuinely cared about getting my car running at its best. HDI Tuning exceeded my expectations in every way. If you're looking for the best in the game for car tuning, look no further than HDI Tuning. Highly recommend!

I am very pleased with the performance of my car. The torque is good. The auto transmission behaves exceptionally well. Fuel consumption is the same as before.When I put my foot down, the car goes, even at speed.This upgrade is highly recommended.

Steve and the team at HDI Tuning, produce a fabulous package for the 1.6HDI. The service is so quick, even from Australia. Plus, it just works; great instructions. The power delivery is impressive, lot more torque. I will get the post-ECU upgrade dyno run in the next week and have the before and after plots. THANK YOU HDI Tuning.
