gt2860rs .64 rear housing overboost gen3 3s-gte, Fixed overboost (atleast so far) Options

Any suggestions? I want to run 16psi, the included actuator should be 12psi but its spiking to 20psi alot faster than i can let off the throttle

am going to pull the downpipe off and test the actuator with a pump, maybe change from 5mm hose to 8mm hose? (Mr Garry's actuator nipple seems a little bigger than Mr CT's)

but has anyone seen this themselves and seen an effective fix short of going external?

if my actuator and door are operating as normal, will porting the gate do the trick? any special tricks?

creep is pretty common with the internal gated 'rs on the 3s...i assume your running a 3" free flowing exhaust?
some guys have installed a restrictor into the exhaust, others have welded the internal gate shut and go external gate.
IIRC jgreening had problems with creep with his setup, and went with a 11psi actuator that would creep to ~14 or somthing like that.
