actuator

[Stefan_s]

hi, i think my actuator is faulty but notsure, when i accelerate it fells pretty laggy and theres a hissing noise that i thought was a leaky dumpvalve but replaced it with a hks ssqv and its still the same, i was told the actuator wasnt working by someone, anyone have any advice?

thanks Stefan

I had the same when I bought mine, you'd see it boost up and then as the revs increased the boost would start to drop on the gauge and you could hear a strange noise. I replaced mine with a HKS actuator as it was on my to do list anyway

well its when i accelerate the boost isnt going up as fast on the gauge as it used to and theres the weird hissing noise and it just dosnt feel as fast

May just be a boost leak or could be actuator I suppose, I assume the problem with mine is it was weak and wasn't holding the boost in the high revs?

Sounds like a boost leak more then anything else. Pressurise your boost hoses and listen when engines turned off (can do it with a compressor and abit of inginuity(SP))

Other then that, replace actuator and try again, there only £5/10 second hand or throw a HKS on if your staying CT9

thanks for the advice, its going to my mates garage tomorow so he can check everything and picking up a hks actuator for £20 so should get it sorted soon
