Actuator not holding above 14psi

[Bakis]

Hey guys, just wanted to pick your brains.

Just got a upgraded/hi-flowed k04 on the MPS and the actuator isn't holding anything above 14psi after a spike to 17psi.

HPF say that i need an upgraded one, does anyone have any thought's on this, from what i've read on MSF the oem actuator should be able to hold any psi you would want to get out of the OEM k04 (17-18psi).

Since this is ported and ceramic coated and running less restrictive mods would that mean 14psi is the best I can get with the OEM actuator?

Any and all help would be great and very helpful.

Power wise she pulled 193fwkw on 14psi.

weird... sounds like a bad port job on the turbine housing
other possibilities, they've removed the restrictor pill in the wastegate lines etc... which would mean you struggle to hold more than 14psi, as spring pressure is 7psi on a stock unit...

How does the spring pressure compare to the psi you can run?

How does the spring pressure compare to the psi you can run?

often struggle to run more than 2x spring pressure
ive got a 10psi spring, towards redline i have issues holding more than 21-22psi
