yeah, in this case more is actually "better" for now, they have two EGRs, one of which taps after the DPF so is more soot-free

The more things you attach to the engine, the higher the risk for a failure.

emissions will get stricter and soloutions more complex, thats pretty likely, but modern gas engines really dont have more things attached to them than early emissions cars. In most cases they have less since they dont have an EGR, dont have a smog pump, dont have any of the strange early fixes really. They manage emissions with computer controls and catalytic converters. Im not going to count electronics, DOHC, VANOS (and similar) or other items like that as DOHC first was used in 1912 and vanos was introduced in 1992 (other variable cam timing schemes were in use in cars as early as 1980) and electronics were arguably introduced for a whole selection of reasons including but definitely not limited to emissions.

This is a little disappointing since I was told it would be coded out. Still waiting for Stan to respond to these latest measurements of the EGR behavior.

not a good sign, hope you get that worked out. Coding EGR out/down would be the biggest reason for me to go this route, and im sure im not alone.
