Many modern vehicles are somewhat ‘under tuned’ from the factory. This provides a large safety factor on all components. This means that most of the engine parts are working at only around half of their potential.
The main reason for this is due to the fact that many car owners will not stick to the recommended service intervals. If you're planning to up the power of your engine, it's important that you maintain it properly.
Another clear cause for ‘under tuning’ a vehicle is to promote sales of future vehicles. If a manufacturer can improve the performance of their new vehicles year upon year, then it is likely that they will continue to sell their newest models and will continue to make profits.
As modern cars are equipped with an electronic control unit (ECU), it is possible for a ‘tuner’ to modify the data stored within it, and increase an engines performance safely. This is carried out in the same manner as the manufacturer would approach it if they were to 'upgrade' the power output of the vehicle.
All of our tuning has been thoroughly tested to ensure the safety and longevity of your engine. If more power is requested from an engine it is important that the service intervals are adhered to. This will help to prolong engine life. At HDI Tuning Ltd we recommend cutting the service intervals to around 6K miles, just for peace of mind. If you look after your car, it will look after you!
What makes a remap safe?
When developing a remap it is important to monitor and log engine running parameters using data logging equipment. Through this, it is possible to ensure the high pressure fuel system (fuel pump, fuel pressure regulator, injectors, rail pressure sensor) and the turbo charger are able to operate as requested and calculated within the remap whilst remaining within safe limits.
It's important not to inject too much fuel as this can raise Exhaust Gas Temperature (EGT) potentially causing damage to a turbo charger; all of our remaps are tested to ensure the EGT levels remain within safe limits.
It's also important to be considerate towards a cars transmission, the rate at which torque is bought in and the maximum torque set is important. If you are worried you may have clutch problems it's best to get in touch with us, generally we recommend fitting a new clutch if it is worn excessively, or alternatively we can produce limited torque remaps.
Took my 306 here today that required more power 😇🙈 all I can say is what a fantastic job he has done. the car has so much more power 😍. He also diagnosed issues that I wouldn't have found. thank you for your 5* service. highly recommended.
I had my peugeot 207 90 HDI mapped for VNT turbo by Steve. The car runs faultless and moves pretty quick. The online service it s very fast, comprehensive and at the right price!
Had my Peugeot 307 136bhp remapped to 170bhp using a BDM100 tool and the online remap service - files were sent back to me the same day which I was very impressed by. Support/service throughout the whole process was excellent, including the DIY guides on how to read/write the files from the ECU. My antipollution system warnings are now a thing of the past and the map itself is great - the car pulls hard right up to the redline now, it's like a totally different engine and I'm quite surprised by how fast the car is now. Well worth the money, I wouldn't hesitate to recommend HDI Tuning.
Great fast service, very knowledgeable, my ds3 1.6 diesel runs so much smoother and faster after it’s remap. Highly recommend this company.
What can I say. I had my 307 90hdi tuned by Ste and he’s done an amazing job it literally means just that.he has brought a whole new meaning to a new lease of life my 307 has never felt this good from 90bhp to just over 125bhp at 275Nm it has become a new animal I would highly recommend he to any one who needs there HDI engine kicking up a notch. 5* service and not to mention he managed to booked me in with in less then a weeks notice. Thanks again mate will be happy to do business again :)
Just had my 206 1.6 hdi remapped with the egr and dpf delete and it's made one hell of a difference. Having egr issues before hand has made the remap even more of an improvement. I defintly recommend HDI Tuning as Steve is great at responding to emails and has given me brilliant advice on what to do to ensure the remap works as it should. Thanks again Steve you have defintly left me with a big grin on my face and wanting to drive the car at every given opportunity.
Remap done by Steve. On hand advice and a wealth of knowledge. Put simple the guy knows his S#*T. After remap had an unrelated fault and Steve was able to diagnose over the phone and it cost me a fiver to fix myself (actually about 50p of vac pipe) but I got plenty left. Cheers HDI Tuning.
Peugeot Expert 90bhp (sluggish), remapped with a Stage 1 Ecu 120bhp (lively). After numerous emails and phone calls to Steve about questions on the Stage 1 Remap I was always put to ease by Steve's quick response, reassurance and honesty. I cannot add anymore to Steve's attitude and personality towards his customers than what everyone has already written. Now after installing the remapped ecu the van started up as normal and everything ran as normal. I took it down the bypass and it just felt a lot lively and lighter.
Had a 1.6D 2011 Volvo S80 throwing up errors from turbo and EGR valve. Car was way down on power and economy. Left it with HDI Tuning for a few days for some work and a remap and the car is more powerful and more efficient than ever before! Previously it would stick around 50MPG on runs of 70-75 mph, now it has just managed over 1000kms to a tank and an average of 58.1MPG. The car has good pull through all gears and emissions do not appear to have changed at all. Delighted with the results!
Steven is a top chap. Sent the files for my Suzuki Vitara via email and totally transformed the jeep. More torque across the whole rev range and gained about 10 mph on top speed. Total value for money. My brother in law is now ordering the same service the day I done mine! 5 star service and 5 star MAP. Thanks again Steven :-)
