Idle and low rpm emissions are usually easier to achieve with port injection because the fuel and air have a chance to mix BEFORE they reach the cylinder and the swirl created as the fuel air mixture passes over the intake valves.
Above idle and lower rpms DI has a big advantage.
Having both is the best of both worlds.
IF ( I won't debate this ) the ecoboost had carbon build up issues the new port injection would cure it.
I have seen quite a few threads complaining about idle quality and low rpm misfires along with needing Reduced plug gap. I'd bet money that issue will be gone on the new motor with port injection.

Some of their conclusions were:
-DI creates more particulates than PFI, but only significantly when the A/F is rich.
-Particulate size is also increased over PFI
-But at higher loads the particulates are semivolatile, non nucleating matter.

They can keep it. The only reason they are doing it is for better fuel economy. I had the Ram with the 8 speed. The operative word is "had." I was more than happy to go down to 6 gears, with fewer problems. Some changes have been great, others have been a nightmare.

Has anyone seen a graph of the new engine torque numbers made at certainRPM? Curious what torque the new motor is making at 2500ish RPM? More or less than the current offering? 420 at 2500 RPM is impressive. New numbers are 470 at an extra 1000 RPM. Worth it?

your assuming your not getting the 420 at 2500 still. Which I bet will be more like 2000. Because they said that was one of the things they worked on.

wonder if they swapped turbos again? Does anyone know about that? That could shift your powerband around a bit.

that's probably where your power band change comes from, the compressor mapping. It may not necessarily mean less lag, but you could get more power out of the same air/fuel situation without adding any noticeable lag. Where the old turbo runs out of room at the higher rpm and air flow, this one probably reaches peak effieciency while still maintaining the same, or possibly better, level throttle response.
Seems like a win!
