Have you guys ever noticed the intake manifold switch from short to long runners on the hemi? Let's say your truck is stoped and you accelerate through 1st gear and have about 50% throttle pushed at about 4k you feel a kick in power. But sometimes i dont feel that kick at all like the intake manifold is not working. You guys ever noticed??

I have felt the feeling like the old vacuum advance would sort of bog down then kick in.

Kinda feels like there is an extra couple of cyl. kicking in. I wonder if this will change as mileage goes up. I only have 1k so far.

Mine does something sorta like that... But to me its in the VVT, mds, and the massive torque management my truck has. Almost like theres 3 different power bands across the rpm range. Once again i say theres a bunch of us waiting on DPS to help us out with these "issues" !

It's the point where the engine torque and horsepower cross on the dyno chart. Most efficient point of operation for the engine.
