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?

make sure to check the downpipe, sometimes the wastegate is not opening completely because it hits the downpipe, so once taken apart the wastegate would operate normally.

and what kind of boost controller are you using ? if it's an electronic boost controller, you will have to set the gain for the new turbo, I know on a Blitz dual SBC the recommended gain setting for a CT based turbo is 5, but that would be different once you go aftermarket.
