what year did EGRS , DPF's, DEF etc..show up on DP's
In other words when were the last good non-emission diesel DPs made. I have a 2008 RAM 6.7 with it and I believe it was the first year so I assume a similar time frame for DPs?

Could you please tell us people that are not up on the current Diesels, what "build them looser" means?
Never heard it called looser, but before DEF they had to use lots of EGR and run them richer to try and keep NOx down.
Once the NOx regs got so tough that the only way to meet them was to use DEF they could then do less EGR and go hotter and leaner getting better power and mileage while putting out 40x less NOx.
