I don't think so. There is a turbo for each bank of the V6. You couldn't have uneven pressure between the two sides.

Turbos spool up equally, they are not staged. They have very small wheels so they spool up faster to reduce turbo lag. Under partial throttle they only produce a few PSI, but open it up and the PSI jumps quickly.

You are correct. The old 6.4 had turbos for low speed and high speed but not the ecoboost.

I remember those, the dual stage Powerjoke turbos. What a piece those engines were!

I had an early 7.3 with the Garret turbo. Great solid engine, but the oil pan was a bump away from leaking due to rust. That engine was a beast, I blew out the spider gears in the Dana 80 on the truck by being a dumbass and flooring it. Caused the axle to hop and BANG, there went the diff.

One of my favorite things is that the torque curve peaks at around 1500rpm and stays there. That's what the turbos are doing for you. The turbochargers are pretty small, but that allows them to spool up fast which helps increase manifold pressure quickly without as much of the "turbo lag" you see on a bigger turbine.

I pull at 2,000 RPM. Whisper quiet. Rarely needs to shift. (5th gear, 60 mph)
