Yea VVL and EGR are nice improvements. The 2016 Pentastar V6 also has new intake manifold with longer runners which helps low end torque.They will be adding variable valve lift and EGR as in the Grand Cherokee, which will offer improvements that Wrangler owners want, like earlier torque delivery as well as a bit more torque.
Without the move to forced air, DI isn't really needed right now and offers more drawbacks than benefits.
The Grand Cherokee with the updated Pentastar has 15% more torque below 3000 RPM and 6% better gas mileage. Wonder if we'll see any further improvements for the JL/JLU/JT application.
