Evolution Chips Exhaust Gas Recirculation (EGR) Valve Deletion service.

More and more vehicle owners are looking to remove the engines troublesome EGR valves from their vehicles as they are getting tired of paying big money to replace them regularly. The problem is, once you do this, you run into problems... If you simply remove the EGR system from the car, but do not disable it in the vehicles ECU, you will likely run into many problems:

The Problems:

  • Detonation.**
  • Poor running.
  • Lack of power.
  • Excessive temperature.
  • ECU Fault light on dash.

** The ECU often alters fuel and spark advance when it thinks EGR is active. If no EGR flow is possible because you removed it, you will have a lean condition which will be further aggravated by advanced timing, leading to detonation.


The Solution:

  Evolution Chips EGR Valve Delete / Disable Service.  

Evolution Chips can safely and correctly remove the EGR operation from your ECU, without the need for you to physically remove the valve itself so there are no tell tale signs that it has been done. (Assuming its in good order of course)

To see if we offer the service for your particular vehicle, just use the vehicle search function in the menu and it will be listed as an option in the results page if we can perform the work on your ECU calibration for you.


A great many unscrupulous so called "Remappers" are just turning off the EGR fault code system so that the fault light doesnt come on the dash for EGR problems anymore. This leaves the system trying to use the valve and in time can damage the engine quite significantly.

Do it once... do it properly!
