it happens right after i left off the gas at low boost in higher gears. never did it until i got the cams in.

i tried both the ix bov and even a turbo xs bov and it still does it no matter what.
at first i thot it was cool but its flippin annoying as crap now

fyi, mods:
crower stg2 cams
epm v2 o2 dump
ams tbe
injen intake/ic piping

my tuner is telling me my o2 might be the culprit in this case.
however, like i said, it didnt flutter/surge (wutever its doing, the noise is coming from the intake) didnt "really" start until after the cams install. it did it a little bit before but it was minor(ive have the o2 dump on for about a yr).

anyone have any clue as to why this is happening?
wuts the fix for this problem?

 

What bov are you using? If it is adjustable lower the spring pressure a tad.

 

i only have the stock 9 bov and the turbo xs. im not sure if the truboxs is supposed to adjustable but i did mess with the spring tension by twisting the top of the bov. still didnt work

 

boost leak somewhere

 

yessir

 

i will do a boost leak test this weekend.
any other ideas?

 

im leaning towards this myself
