Works well for most Davidd, would be a good idea to install a exhaust temp sensor, (VVT) Variable vane turbo's on some diesels dont take kindly to the removal of their auxilary cooling system being inert gas from the EGR.
My EGR valve is stuffed (noisey), can hear it cycling flat out after heavy use due to higher exhaust temps.
The EGR on a diesel does not have the same effect on the exhaust pollution as a petrol engine, it has no benifit in regards to pollution other than cooling the turbo.
If you work your rig hard i advise a exhaust temp sensor to ensure you dont detonate the turbo/engine.
