Frequently Asked Questions
More Power, Less Fuel, Better Performance!
What are the benefits of an EGR delete?
EGR systems cause significant problems, especially for vehicles doing lots of short-distance or stop-start driving. The EGR valve operates most when your engine isn’t under full load, which leads to excessive carbon build-up that chokes your engine.
This carbon contamination causes several issues:
- Reduced airflow and poor engine breathing
- Excessive heat build-up
- Sluggish throttle response
- Higher fuel consumption
- Potential engine failure if left untreated
An EGR delete restores proper airflow through your engine, preventing these problems and extending engine life. The result is cleaner combustion, better performance, and improved reliability.
Chip Tuning/Tuning Box or ECU Remapping - Which should I choose?
ECU remapping is the safer and more effective option for your diesel vehicle.
Tuning boxes are external devices that manipulate engine sensors to trick your ECU into increasing power. While they might provide short-term gains, they often compromise fuel efficiency, reliability, and safety. These devices use a generic approach that doesn’t account for your specific engine condition or driving requirements, potentially causing long-term damage.
ECU remapping works differently. We modify your engine’s actual software to safely optimise power, torque, and fuel economy. By working with your vehicle’s existing systems rather than against them, ECU remapping delivers a tailored solution that maintains engine safety and reliability.
At Advanced Tuning Solutions, we only offer ECU remapping because it’s the professional standard. Our custom approach includes comprehensive vehicle assessment, live data logging from your specific engine, and tuning that’s matched to your driving needs and engine condition.
If you want reliable, long-term performance improvements, ECU remapping is the clear choice.
How does ECU Remapping work, and what do you change?
Modern diesels come with conservative factory settings designed to meet global regulations and varying fuel qualities. Your ECU controls everything from turbo boost and fuel injection timing to exhaust gas recirculation, but it’s programmed to prioritise emissions compliance over performance.
ECU remapping modifies these factory settings to optimise your engine for New Zealand conditions and your specific driving needs. We adjust parameters like turbo boost levels, fuel injection timing, fuel pressure, and sensor scaling to unlock your engine’s true potential while maintaining reliability.
At Advanced Tuning Solutions, every remap is based on live data logs from your specific vehicle. We don’t use generic maps – we create custom tuning that accounts for your engine’s condition, your driving style, and what you want to achieve.
The result is a more responsive engine with improved power delivery, better fuel economy, and smoother operation that’s tailored specifically to how you use your diesel.
Can the ECU be restored to its original state?
Yes, your ECU can be restored to its original factory settings if needed.
We always keep a backup of your original factory file before making any changes, so reverting is straightforward if circumstances require it.
However, once you experience the improved performance, fuel efficiency, and drivability of a properly tuned diesel, most customers can’t imagine going back to the restricted factory settings.
If your tuning files are ever lost due to dealer actions or component failure, we can reinstall your custom map. There’s a small service charge to cover our time and travel costs.
At Advanced Tuning Solutions, we stand behind our work and ensure you have options throughout your vehicle’s lifetime.
What happens to my fuel economy?
Most customers see improved fuel economy after ECU remapping.
With more torque available at lower RPMs and optimised combustion efficiency, your engine doesn’t need to work as hard to accelerate or maintain cruising speeds. This translates to less fuel consumption during normal driving.
A professional ECU remap from Advanced Tuning Solutions typically delivers fuel savings of 5% to 15%, depending on your vehicle model and driving conditions. The improvement comes from better engine efficiency, not just changing your driving habits.
The result is a win-win: better performance when you need it, and lower fuel costs for everyday driving.
How long does a remap take, and where can I get it done?
A professional ECU remap typically takes 3-4 hours to complete.

"I can get this cheaper elsewhere"
You might be able to, but it’s worth asking yourself: What are you actually getting?
Many providers offering heavily discounted remaps cut corners by using generic, pre-purchased files that aren’t tailored to your specific vehicle. While this might save you money upfront, it can lead to drivability issues, reduced reliability, or even significant engine damage.
At Advanced Tuning Solutions, we take a completely different approach. Before any tuning begins, we conduct a comprehensive assessment that includes taking your vehicle for a test drive, capturing live data logs from your specific engine, and performing a thorough physical inspection. This diagnostic process ensures we understand your vehicle’s current condition and can create a custom tune that’s safe and optimised for your engine.
We’ve seen the costly consequences of cheap, generic tunes – failed injectors, damaged turbos, and transmission problems that end up costing thousands more to repair than investing in proper, professional tuning from the start.
The truth is, quality work isn’t cheap, and cheap work isn’t quality. Our comprehensive approach takes more time and expertise, but it delivers reliable, long-lasting results that protect your investment.
I have issues with my EGR System, DPF Light, or AdBlue warnings. Can You Help?
Absolutely. At Advanced Tuning Solutions, we specialise in EGR, DPF, and AdBlue solutions that permanently resolve these ongoing problems.
These emissions systems are notorious for causing issues in modern diesels. EGR valves clog with carbon, DPF systems require constant regeneration cycles, and AdBlue systems suffer from crystallisation, sensor failures, pump malfunctions, and contamination issues. These problems create warning lights, reduced performance, and expensive repairs that only get worse over time.
We offer permanent solutions through EGR, DPF, and AdBlue system removal combined with custom ECU programming. This eliminates all three problematic systems entirely, restoring proper engine operation, improving fuel economy, and preventing costly breakdowns.
Our approach addresses the root cause rather than temporary fixes. Once completed, you’ll have reliable operation without the constant headaches of emissions system failures.
