So ya save all emissions for 300ks then let it all out in one spot
Large trucks have engines that arnt lasting as long with all the egr gear on them. so greenies . we have to smelt more iron to repace worn out engines that save the enviroment, hmmmmmmm

Are the valves that work the barbed ones from ebay below?
They look different.
The 4mm bore emission hose, 'T' connector and small black cable ties are easily sourced but can you ID the air diffuser to help source that?

Apart from better performance, better fuel economy (if done right), smoother running, lower egt's at cruise (dependant on how it is done), cleaner engine oil between changes, no degradation of performance over time due to carbon build up in the intake manifold, better reliability, longer engine life etc, etc, etc... apart from that why would you need it?

That sounds like a brilliant solution! If only I understood the theory?
I think the Scanguage will only read the throttle valve but another gauge reads the EGR valve too. There were some posts back in this thread, I think, that gave values for both.
If you can't find them or the posters let me know and i'll find it.
Basically I think they oppose each other. When the TB is at 100%[open] the EGR valve is closed and when the TB is at 20% the EGR valve is open.
