When i'm stepping on it, it's loud in first gear then the bvp seem to closes and build boost in second and each gear afterward. Is this normal? I understand that it's suppose to open when not in wot but shouldn't it close when i'm gunning it in first? thanks in advance for the explanation. I did search but nothing noting this loudness.

 

its cuz your blower is building boost so fast in first it will scream like that... they all do it

 

my car is faster.

 

haha, i always knew that was why it was loud

 

hahahaha

 

nope mine is.
