We’ve seen from online reviews and DIY’s that people have tried to just Blank-Off the EGR valve and at first, experience some excellent gains..

+10mpg gains
Better Throttle Response
But soon after, they begin experiencing problems with the EGR Valve being blanked off..
Sluggish in low rpm
Down on power & a loss in mpg
Poor Throttle Response
Why does blanking the Peugeot 307 HDI EGR Valve system cause these negative effects?
If the EGR valve is blanked off, then no exhaust gasses will recirculate back to the intake manifold and into the engine. – However, the engine ECU does not know that you have blanked off the EGR Valve, so when the Engine ECU calculates how much diesel to inject on each cycle, it will be doing so with the EGR flow included in it’s calculations.
In order to properly remove the EGR valve and stop it recirculating exhaust gasses without the negative effects as described above, you will need to have the engine ECU remapped accordingly to tell the ECU that the EGR valve is to remain shut at all times. The engine ECU will then re-calculate the injection cycle to compensate for the EGR valve being closed and thus you will experience true benefits of having the EGR valve removed.
