Question for those with KY on F23

Does anyone else have KY stage 2 on their F23 transmission?
If you do, where is the engagement point? low (pedal almost to the floor) or high (about one inch to the top of the pedal?
Using oem clutch rod.

I have been having issues since the change of clutch. My clutch engagement is high after the install. (breaking period etc etc)
The clutch would slip on anything above 5psi of boost. When in does, the clutch engagement changes to low. It gets spongy up top.
I bled it again, same thing (pumps, open/close valve, repeat, etc). Did like a small flush, open clutch bleeder valve, and let the gravity bring out the fluid as I pour more up top to keep from going down. The fluid was dark, after seeing some new fluid I keep going a little more then close valve and top off. Still slips and engagement points changes.
Car shift normally, it goes into all gear without issues.

Now more in the morning, cold starts, the clutch engages low, but later on when I drive it changes to high engagement...... but it always the same; is high then when it slips it goes low.
I'm like wth is going on.....

Was thinking on changing to a high temperature fluid.
Or more bleeding require?


Parts used on the clutch change: new OEM flywheel, KY stage 2 clutch kit, same TOB had about 2k miles, a OEM new master cylinder (zzp ajustable died for some reason), 2qt of dexron3 (non gm or mobil 1)


If i lost you or need more info, just ask....

Thank you

I dont think it has anything to do with the hydraulics if its slipping on 5psi. Sounds like its not fully engaging.

Did you torque everything to spec?

Did you clean the oil off of the flywheel and pressure plate surfaces?
