Need help: 2004-present Nissan Titan/Armada VK56DE engine

[Prestb]

I've got a fun one here; I need some help finishing this recreation. I've looked through a bunch of stuff explaining the build of the VK56DE and I've currently got it built up quite accurately ingame, but I don't know how to fix the performance curve and I also can't figure out how to increase Torque without botching up the Horsepower. I've attached the engine file to this post for you to look at if you want.

My GOAL is ~385lb-ft/3600 rpm and 317 hp/4900 rpm. Not sure if I could possibly make it that accurate ingame, but hopefully close with some help.

I've got the right block material, almost exact stroke and bore measurements, compression ratio, etc. I couldn't find any "low-friction molybdenum-coated pistons" option, so I went with a similar alternative. Even got exhaust measurements and mufflers correct I believe. One thing that I didn't really get was the Nissan CVTCS thing.

According to wikipedia, the version of the VK56DE you were trying to recreate didn't start production until 2012.

Here's a recreation I just made of the 2004 version:

Like yours it doesn't make enough torque and makes power too late, but it does make torque at the right rpm.

I see. Any idea on how to increase just the torque then? Other than that, good job on making that 2004 version. I'm gonna keep toying around with mine until I either figure it out or give up and start on something different.
