Since I've installed the T'netics kit, I've noticed that I can hear this ticking sound - and at times in the morning when it's colder, I can hear the ticking louder.

The sound is traced back to the VSV - a Vacuum Switching Valve that is normally located on the stock intake box. It has a couple of vacuum tubes connected to it, and a sensor as well.

This thing ticks a lot - is it faulty? I'm not getting any codes.. Here's a pic of it (however as it sits now, it's zip-tied to my Greddy strut tower bar.

It's supposed to tick like that. Do a search on VSV ticking and one of our members has a fix that muffles the ticking sound by a lot lol. Just cant find the thread, sorry.

iv heard about it from more than one person who is boosted.........I'm just throwing an idea out there but i think it has to do with the pressure that we subject to it when we boost......i don't know if we really harm it cause i haven't heard anyone complain except for the sound it makes.......though it does make you a little nervous

^ I have a picture to show you when I upload it after work. I have a small scrape + chip on my cam lobe. VERY MINUSCULE!

im thinking of taking some sort of insulation to wrap around the bastage to muffle the sound

Yeah I figured it was normal (because the stock location had a rubber grommet to deaden vibration) but I just wanted to be sure.

Now I gotta find a good way to mount it - it's zip-tied to my strut bar now, which makes the ticking louder.. lol
