CM2450, whats is this animal?

[Chamberpains]

I have a buddy that is the fleet maintenence manager for a medium sized flatbed company. Talking to him yesterday about some problems with my engine and he mentioned he just finished up his certification on the newest cummins CM2450. He said they are not the X15's but the new 2021 model coming out. Any one have any news on them? He said they cut the EGR down to close to 1/3 so it sounds like it possibly could solve a lot of soot issues. I'm just being lazy and not researching it myself. So I'm just throwing it on here.
