i'm probably going to go with the HKS actuator that's made for the S14 T28.
considering it's rated around 14psi max if i set it alittle below it'll be safe even with a little boost spike...then if i'm having problems with climate variability, spring stiffness, spikes i'll control it with an ebc.
why do people stick with the stock actuators and push 14psi....because it's cheaper?
