I already searched about flutter. Mine is still fluttering at low rpm even in 1st gear. Getting different bov will help reduce flutter? or same?
checked all pipes and hoses and they are not leaking. I like how stock bov sounds when i boost but kinda sux when i drive around block and flutters when i shift gear everytime.
yes bov is in correct direction
using injen intake

 

this might help, but only if your not stock licp

Still sounds like it's backwards

 

Backwards +1

 

its on correct direction. i guess i'll pull it out and switch side and test

side part goes to intake
bottom part goes to ucip

btw it holds boost fine but flutter noise at low rpm is really really annoying.

 

Sounds like you have it correctly installed as I too have the injen piping. Might just have a messed up bov, my stocker doesn't flutter at low rpm.

 

could be the air filter?
i have cheap cheap ebay filter for now.
Had K&N and it reduced flutter noise.
i'll try different bov first

 

What BOV do you have? Also list all your mods. When you say flutter, whats it sound like. At full boost when you discharge does it make a turkey call sounds, like pshhhh wa wa wa. Or are you talking about low boost discharges? Explain the sound & its easy to fix.

 

low boost discharge. its fine when i actually push my car to boost. but when i drive around block at 20-30mph and shift around 3k, i get that turkey sound.
wa-wa-wa
lol turkey sound
using stock 9 bov

tbe, injen uicp and intake

 

Look, if the stock DV is in backwards I don´t think it´ll flutter at low boost levels. At least that has been my experience. I installed mine in backwards once and it didn´t vent or open at all.

It sounds to me like you could crush it a wee bit. I went too far with mine when crushing, so be careful!

 

if nothing is modified at all see if the dealership will fix it under the b2b warranty

 

how are did you install your boost controler?

 

its normal....mine 8 plastic one did it and so does the 9 bov i put on as well
