standard actuator

[adz_sportif_turbo]

i noticed that the spring in the standard ct9 actuator is rediculously soft!! if i uprated this u think it will aid in throttle response?? im running standard levels but surely its leaking boost out before i hit full...slowing spool time, and what is the HKS actuator running if i just plug and play??

also can someone define the term "gain" on a boost controller please?? i kno if adjusted right it spools the turbo quicker but how does it do that?? does it adjust when the actuator sees boost??
