I'm currently using a defi boost gauge, and there is a lot of chatter going on when the engine is warm at idel. Is this normal? I can hear the vsv, it makes crazy ticking noises when I'm stopped and I was wondering if anyone else has experienced this.

 

i hear the same thing.

 

yea I have it two and sometimes the frequency changes. It seems to be faster the warmer the engine gets. The sound got amplified alot after installing my intake

 

THAT NOISE IS THE VSV FOR THE EVAP TO THE CHARCOAL CANISTER ITS NORMAL. SORRY FOR CAPS

 

Ok, we've established the sound is normal and the valve is doings it's job, but should it create so much instability in the vaccum?? My gauge bounces +5 to -5 to the beat of that tick. Are there any boost gauges out there that might filter that out?

 

ditto

drove me crazy trying to find wat it is at first
