The start-stop function was initially invented to lower fuel consumption and to reduce emissions by cutting the engine when the car is not moving (example when waiting at the red light ).

Altough it saves fuel and looks like the perfect system, a lot of users don't like it. It just kicks in when it doesn't have to...

When we disable this system, the car will have a better throttle response (SAFER!) and the lifespan of your car's battery & starter-alternator system will be significantly bigger!

Another advantage is that your air conditioning or heater system will continue to work while standing still,

Downside will be a slightly increased fuel consumption.

A widely adopted route to reduce NOx emissions is the recycling of exhaust gasses (Exhaust Gas Recycling or EGR). This involves recirculating a controllable proportion of the engine's exhaust back into the intake air.

A valve is used to control the flow of gas, we can disable this valve ( thus called EGR-OFF ) so your engine will remain clean and you have no more issues with EGR.

Is your DPF clogged, regenerating frequently or giving you any other kind of troubles ? The solution is very easy, just get rid of it and your problems are solved.

Furthermore, removing the DPF will result in increased performance and turbocharger lifetime while reduced fuel consumption and is far cheaper than to replace the DPF by a new one.

As many modern cars are equiped with a SCR or DeNOx catalyst, they require AdBlue fluid to clean the catalyst, a lot of people don't like this and want the function disabled.

If not refilled in time, it will prevent your car to start and the price is high, not only for the product but also if you need to replace AdBlue parts out of warranty!

The main advantages of deleting the SCR/AdBlue system is increased performance and no need to fill up theAdBlue tank anymore

When deleting the SCR catalyst / Adblue system, the car will not meet emission regulations anymore
