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?

When I ordered my rig I demanded a non DEF motor and they found one somewhere. So I have a 2008 rig with what I'm told is a 2006 Cummins motor. Kinda rare I believe. I generally get close to 10 MPG but never run my rig past the torque curve at 62 MPH/1450 RPM.
