@Compu There's three solutions that I've found that've helped.
1. Decrease the amount of power your engine generates - the more power your engine generates, the more the RPS will jitter. Consider using a more lean AFR, lower engine RPS, decrease cylinders, etc.
2. Place a dial onto your creation, read, at whatever clutch value your RPS jitters, and use a clamp on the clutch at 0.02 or 0.05 clutch lower should solve the issue. Since you're limiting your clutch- you can then increase the gear ratio toward your engine and it shouldn't jitter since it's clamped at where it used to jitter.
3. Go into the Clutch Controller and manually set the minimum value to a negative number. The clutch controller will still work and should resolve your issue. If it doesn't fix it consider using a different clutch.

even with a sensitivity at 0 the RPS still seems to jitter at high load

You are a life saver. None of my stormworks ideas would move and inch without any of your controllers.

perfect!

Yes.

can i use this on my creations if i link it?

You really did magic on that one. Really a plug and play marvel. Good work man.

It just lowers the clutch input depending on current RPS, so you should switch clutch value to 0 on neutral gear in your mc.

yo uran, what if i have a neutral gear? wharr i do?

Hey, coolcat you stole my joke!

sw user try not to yell "stolen" in comment section challenge (impossible)

Oh lol, I got the formula from a discord server a while back. This is cool though.

No, it is part of my drivetrain controller , which was published and updated earlier than yours. Anyway, the clutch formula is very simple and they matched coincidentally.

Literately stolen H-Tech controller smh.

Outstanding!
