15 & 16 LML Emmissions Friendly Stock VGT/ S369 SXE Compound by Wherli

Took a stroll thru the Wehrli website and came across this turbo set up. With all the uproar about emmissions & bla bla bla I figured i would post this for the LML guys looking to get some more power and stay compliant.

I figured I'd throw this out there, but after looking at this kit I'm questioning a few things. My understanding thru research and talking with others in the diesel industry is that the 369 SXE with the 73mm turbine is a lot more restrictive than the VGT chargers with the vanes open. Due to this wouldn't the drive pressures be thru the roof at higher power levels or will that all be controlled thru the tuning making sure the vanes in the VGT don't outflow what the S369 turbine can handle?

I seen that a little while ago too. They say up to 650 rwhp.

But would the drive pressure be any greater running this compound setup vs running this 369 as a single?

I should be around the 600 hp or possibly a little over, not sure exactly. All I know is it's more than the stock transmission wants to take a regular basis so I've been trying to take it easy lol.

I see over 60 lbs of boost under full throttle on my biggest tune so it definitely rips pretty good.

And I just have the normal tune that Kory offers for my setup, position 1 is just a lot less fuel than position 5.

Now that you say that i'm guessing it would be close if not the same as to running it as a single since its the low pressure turbo in this specific set up that would be the choking point.
