It makes life incredibly easier and remapping cheaper. TD Performance economy tuning services provide a quick ECU software update to boost fuel efficiency. A significant increase in torque allows smooth power delivery and less gearshift, improving MPG and driveability.

Economy remap is for turbo diesel only.

Stage 1 Tuning

TD Performance provides the most cost-efficient way to remap any vehicle to performance. It is specifically designed for standard vehicles with no hardware upgrades. Stage 1 remap removes flat spots, re-characterizes torque, and ultimately provides responsive drive without any glitches.

Turbo diesel and turbo petrol vehicles greatly respond to stage 1 remap, and customers see a 20-50% increase in BHP and torque.

Stage 2 Tuning

Stage 2 tuning provides more significant power gains than stage 1 but will require additional hardware upgrades to stay consistent and reliable. It further removes flat spots and aggressively boosts the engine’s functionality.

Stage 3 Tuning

It involves a next-level remap to be invested for the track. It’s pretty expensive and requires tweaking inlet valves, intercooler, cylinder head, head gasket, and spark plugs. Stage 3 tuning will completely alter your vehicle into a more advanced and improved automobile.

Contact TD Performance Tuning with your car’s model and specs, and we will customize the whole remap and advise the required hardware upgrades.

DPF Removal

DPF removal is the best solution for enhancing efficiency and performance. That is what our engineering team is dedicated to, always looking for the best DPF removal solution.

DPF faults and regenerations are covered by our lifetime guarantee every time we perform our DFP removal procedure. We also offer you our excellent customer care service. We are always available to discuss any vehicle-related problems related to our expertise and guide you accordingly.

First, the exhaust system is disassembled. During this procedure, the outer casing isn’t removed and kept in its place. It involves the removal of the internal filter from the exhaust system. We disassemble the exhaust system first and make a window in the top from where we take out the filter.

The window is then welded back, and the DFP canister and exhaust system are put back in their original positions. If you want to keep your original DPF canisters intact, don’t worry, as we can use DPF bypass pipes to do that.

The next step is to cover the software aspects, in which we reprogram the ECU. However, the process isn’t only physical. We reprogram/remap the Electronic Control Unit (ECU) and remove everything related to DFP from it.

Now, why do we do it? Because it will not cause any issues in the future by not sensing the missing filter and creating false alarms.

If it isn’t done properly, the system will keep warning despite the absence of the filter. It ensures that the software doesn’t sense the missing sensor and bars DPF regeneration and warning lights.

We can also remap the ECU at a discounted price, which means better fuel efficiency and performance. Removing DPF also ensures there is less turbo lag and reduced maintenance costs. You can always contact TD Performance Tuning for getting a quotation on the DFP removal.
We sell our DPF service for off-road use only. Removing DPF makes your vehicle illegal that can’t be used on any public road, so seek further advice before going for DPF removal.


Adblue Deletion

To reduce NOx levels, a special chemical liquid called Adblue (also known as Diesel Exhaust Fluid or DEF) prepared by mixing urea and demineralized water is used. It is used in Selective Catalytic Reduction (SCR) on diesel in the exhaust system, which converts NOx into nitrogen and water vapor, thanks to a chemical reaction.

It is a complex system involving sensors, modules, pumps, making it hard to maintain it. Moreover, vehicles used on a regular basis use a lot of Adblue, meaning you often need to refill your tank.

We disable the Adblue system and remove the related dashboard and warning lights by reprogramming the engine management system. However, we sometimes need to install a small, hardwired electronic unit in the vehicle for this purpose too.

Please note that vehicles with Adblue deleted are not legally allowed on the road, and we provide this service only for off-road cars. Moreover, we provide this service for cars exported outside the EU to countries with different regulations, so it is on you to declare that your vehicles have been modified by the relevant authorities.

As you see, this service is primarily software-related and hasn’t got much to do with the physical/hardware side of things. However, the inclusion of the electronic unit balances things out a bit.


EGR Removal

The new regulations from the EU and Governments regarding emissions have forced manufacturers into fitting an Exhaust Gas Recirculation (EGR) in their vehicles.

It has undoubtedly resulted in fewer emissions, but there has been a significant downside to this strategy, too, which cannot be ignored. However, they have compromised the efficiency of vehicles in doing so. It has also badly affected the reliability of engines and has made their lives shorter in the long run.

How does this system work? It works by putting the exhaust gasses back into the combustion chamber. It is done when the loads on the engine are lower so that the combustion temperatures can be reduced. With this recirculation of the exhaust gasses, the Nitrogen Oxide (NOx) emissions are reduced considerably.

Engines not only need fuel but oxygen as well to function properly. However, the EGR system halts the availability of oxygen to the engine, which results in all sorts of troubles. If an engine doesn’t receive an adequate amount of oxygen, it results in it becoming extremely slow and eating up even more fuel.

The EGR makes the dirty gases clog the valve, which results in a lack of oxygen for the engine, making it lethargic. Sometimes the vehicle is rendered undrivable. It reflects in the electronic performance of the EGR valves, too, because the internal motor and position sensor fails.

Indeed, anyone would want to get rid of such a system, and we are here to do it for you. The customers are now well aware of the downsides of this system, as it results in high maintenance costs and long-term reliability issues, which makes them change their vehicles more often.

TD Performance ERG removal results in better throttle response, fewer maintenance costs, more power, enhanced fuel efficiency, extended engine and turbo life and a cleaner engine with more oxygen.

We remove the EGR by first blocking the exhaust gasses from entering the valves. It is required only when the valves are unable to close themselves due to excessive carbon build-up.

Second, we remap the ECU by either removing the ECR functions altogether or the valves are permanently closed electronically, a critical step for preventing mishaps in the future.

This electronic closure of the valves is critical because if it isn’t done, the valves will stay open. It will result in the same problem that we are trying to resolve, which is stopping the exhaust gasses from going back into the combustion chamber. Our state of the art software support ensures that this solution works perfectly and there are no mishaps of any kind in the future.


Speed Limiter Removal

The speed limiter is a type of gentleman’s agreement between different car companies, as all of them apply it to their respective vehicles. It is either applied at the factory, or a third party does it later. For instance, many BMWs and Mercedes have speed limits of 250 KMH/155 MPH set from their factories.

We remove the speed limiter by adjusting the ECU data. It works for most vehicles, and our authorized dealers are well-versed in the procedure. However, some vehicles have a more complex system that needs a more profound examination.

Those speed limiters can only be removed at our HQ in Houghton Le Spring. So, contact us today with the relevant information such as vehicle details and location to discuss the issue in detail. There is also a special discount on this service called the fleet discount. Please contact and share your requirements

Lambda Sensor Removal

Decatting a vehicle often results in an unintended consequence, which is the illumination of the engine management light, resulting in storing a fault code in the ECU memory. We disable the second lambda sensor by recalibrating the ECU data, which can remove this error from the system.

The second lambda sensor is responsible for monitoring the catalytic converter efficiency. When we disable the second lambda sensor, a Decat pipe will be used on the vehicle. The engine management light or any other fault codes won’t be triggered because our service ensures that the faulty code is permanently removed from the system.

P Code / Fault Code / DTC Delete

When we perform modifications on a vehicle related to swirl flaps, EGR, DFP, etc., there are high chances some fault codes may get stored in the ECU memory and the dash lights and limp mode.

However, these fault codes can be permanently removed, and we can do it perfectly. By eliminating the codes, we remove the possibility of dash lights displaying and the possibility of the vehicle entering limp mode.

In short, TD Performance Tuning provides a one-stop solution for all the remapping needs of your vehicles. Contact us today and see your vehicle transform now.


Inlet Manifold Swirl Removal

Swirl flaps are butterfly valves in diesel and petrol engines used to regulate fuel to air ratio and improve torque at lower speeds. They also help with improving emissions.

When the engine load is light, these flaps close, and the air goes into the combustion chamber, where it helps combustion and helps with generating more torque. At 2000 rpm and above, the flaps understandably open fully and don’t affect the engine performance and emissions much.

The Problems with Inlet Manifold Swirl

There are multiple problems with inlet swirl flaps, and the first one is the potential engine failure that could result from their usage.

The metal screws that hold these flaps can break loosen anytime and end up in the combustion chamber resulting in severe engine damage. These mechanical failures have resulted in many accidents in the past so removing inlet swirls is a wise choice for any car owner.

Sometimes the seal around the flap spindle is damaged, making the air for the inlet manifold flow outside. This lack of air makes an engine run rich, meaning it receives too much fuel and too little oxygen. Ultimately, it damages other vehicle components such as DPF, EGR, etc.

Breather system oil and EGR system carbon can both combine for carbon build up on the flaps, which denigrate a vehicle’s performance by shrinking the inlet manifold size.

Modern vehicles do have actuators to open and close the flaps, but those too can fail with the sensors going down with them. As a result, the engine performance and engine management light are severely affected.

The Removal Procedure

Removing the flaps depends upon their current physical condition. If they’re in good condition and the fault lines with the electronic actuator, we will disable the actuator function instead of removing flaps and fixing what isn’t broken in the first place.

Any Negatives?

There are no noticeable downsides to this procedure. Some may point towards the possible drop in performance and efficiency. Still, you must remember that carbon build-up is a natural phenomenon that starts from the very first minute of a running vehicle. Instead, you may see an improvement in performance and efficiency when these flaps are removed.

The costs depend upon the flap and designs. Contact TD Performance Tuning with your vehicle registration, and we will be glad to discuss it with you.
