Its not a lot but i have some money to spend.
I found a CBV off VivaPeformance.

And another off IPD

Now one is significantly cheaper.
Now which one is better?
I read they change the sound of the turbo and help the turbo.
But is there a difference??

And i was interested in a new TCV
IPDs version which seems pretty nice.

should i get it? Is it worth it?
Or this one off Ebay which is cheaper.

When i drive i do notice a kind of weird noise from when i accelerate like theres fluid somewhere but only at certain rpms i believe.
I dont notice anything bad but it just sounds strange.
It seems like it is coming from the turbo could i maybe use this to help things?

I added a boost controller for $50 in. and i believe it increased my boost but i dont notice it getting any higher when i mess with it,
could it be at a certain point that may be stopping it from getting higher?

Thanks for any feedback guys.
Sorry about all the questions and links!
