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.

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.

Top class. Ordered the Dimsport Mygenius and the stage 3 map for GTD1244VZ conversion (for bluehdi peugeot partner). Very quick to send back the file and always got back to me about any questions or issues I had. The difference in the van is night and day, more than happy with it! Pulls like a train.
10/10 service. I'd recommend to anyone!

After having issues with the ECU in my BMW for 8 weeks (the car was left at a garage to be fixed) I finally found Steve who could help and had me back up and running in a week. Top service! Thank you Steve!

Very good, I am glad that I chose this company since I am from Romania. The car runs according to the data displayed.
I chose from them the soft tuning option for Ford Fiesta 1.6 16v TDCI 90 Mk6 Stage 3 Remap – Option 2 (155 BHP | 320 Nm)

I personaly used their online remap service twice for my 2010 Volvo V50 1.6 16v. First a stage 1+ over a year ago with great result, and lately using their online guide a GTD1244VZ upgrade with all the other supporting mods and new map to suit and the whole package made a masive difference with super quick turbo spool and great power all the way up. I highly recomend HDI Tuning, they know their stuff, very professional and plaesure to work with.

I have a 2015 Peugeot RCZ 2.0 HDi and purchased the Stage 1 upgrade. So it's close to 24% more torque, 17% more power. I did not know what to expect but was pleasantly surprised. When driving gently I could not feel any difference. You need to call for that torque.....and pressing your right foot you immediately notice the difference. The car pulls like a train and accelerates better in all gears. I really like the progressive nature of the tune. Can't comment on economy yet, too busy driving hard and having fun. It's a more enjoyable car to drive, and it was great fun before the remap. Very glad I had it done and it added about 15% to my insurance premium. Top work HDi Tuning. I would not use anyone else for Peugeot diesel tuning. Also great customer service with emails answered immediately.

I recently purchased a 2014 fiesta sport van. With it only having 95bhp i looked into getting it remapped. I had seen alot of good reviews on HDI Tuning on social media platforms so I decided to get a stage 1 remap using the mygenius obd tool. It was so easy to use and great communication from HDI Tuning, I didn’t realise that my van had already been remapped previously to me buying it. The difference between the previous map and HDI Tuning’s is night and day it as totally transformed the van. Would highly recommend HDI Tuning and the mygenius obd tool as it’s so easy to use

I am very happy with my remap with Steeve. I have a BMW X6 40d, which I had already had remaped by someone very well known on the BMW forums in the USA. Even if at first the car seemed to be more efficient, when you got to around 180 km/h, the turbo cut out and it was impossible to go beyond. The car was restricted and that was very unpleasant, you had to connect the OBD and erase the fault code that appeared each time, I changed several parts but nothing, I even almost changed the turbo! Also black traces of the DPF on the rear bumper were common. I contacted Steeve, who had already remaped my old Peugeot 206 in the past which was a bomb. So he remaped my BMW and it's night and day with the previous remap, the car no longer cuts out at high speed, it is much more efficient and no more traces on the bumper. It's so clean that it looks like a stock remap from BMW with a significant performance gain. It's professional work. You can entrust him with your car with your eyes closed, and he's not a thief, I paid half the price for my remap!

I have used HDI-tuning a number of times over the years and have always been happy with their responsive service and products. The remap has completely transformed my Ford 2.0 dw10c eu5 engine

I have a peugeot 308 1.6hdi. I got a stage 1 remap and it works brilliantly. The communication with HDI Tuning team was fast, efficient and very helpful. I also had no problems swapping back to factory settings if needs be.

Ordered a online remap from hdi tuning and a my genius obd programing tool, everything worked spot on and was such an easy process. The order was delivered next day and the online remap service only took a couple hours. Can't recommend hdi tuning enough!!

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.
