yea,
I had 2 check valves on....& it would only throw a cel when I was in 4th gear tryin to boost 2psi,
now it will kick on when I'm in 2nd gear @ about 3-4psi

I'm still searching & searching about this flutter/surge I have,

I'm reading about the stupid hks not working under low boost...
or the friggin things broke,
I tried to take the vacuum line off & it pulled the whole nipple of the bov off


well...I do have a 3bar map sensor..
but I would have to have it tuned for my car wouldn't I

a friend was running it fine on his dpfi civic...
(just a thought)...but check valves will do

well....n/m,,the 3bar was just sold
