Discovery 3 lack of power & poor mpg: What was the cause?

A local farmer came to the JGS4x4 workshop complaining that his Discovery 3 2.7 TDV6 was experiencing a lack of power, poor mpg and he was finding the Discovery 3 was reluctant to start.

We ran the diagnostic to find out the Discovery 3 was experiencing a faulty, sticking EGR valve. Improve mpg and torque with a monster remap

What is an EGR Delete and why do we do them? >

Installation procedure

The JGS4x4 team performed a Monster Remap with an EGR delete and soon sorted that problem out!

One of our JGS4x4 technicians will connect to your vehicle’s ECU or ‘brain’ with a laptop PC, through a diagnostic socket. The current engine management default program will be read from the car. Certain operating parameters including fuel pressure, boost pressure, timing, and others are adjusted and uploaded back to the ECU.

ECU remapping will not only improve the engine’s power and torque figures, it will also sharpen the throttle response and widen the power-band. This will make the power delivery a lot smoother, which in turn will make the vehicle feel a lot livelier to drive and the engine more flexible. It will make driving easier with fewer gear changes & improved acceleration.
