EGR Delete ECU Tuning

The main benefit of an Exhaust Gas Recirculation (EGR) system is that it recirculates some of the engine's exhaust gases back into the engine. This reduces emissions. However, the downside is that exhaust fumes containing carbon deposits are constantly being recirculated through the engine. Over time, this can cause a build-up of carbon deposits in the intake manifold, etc. which can contribute to the failure of the EGR system itself. Replacement EGR valves can be expensive, and in the case of high-mileage engines, the continual carbon build-up can eventually lead to total engine failure.

Removal of the EGR system by blanking off the exhaust input and reprogramming of the engine management ECU results in lowered engine temperatures, improved throttle response and economy, and also can lengthen engine life by reducing oil contamination and carbon deposits.

An EGR delete consists of ECU delete to remove the system. The benefits include an improvement in engine performance, fuel economy, and not having to worry about emergency maintenance on the EGR (or even the engine itself).
