I am just trying to find out if i have my BOV/BPV spring set too tight, every now and then i hear a ch,ch woosh instead of a clean woooosh you normally get when its venting.
Is this becasue the spring is too tight, it seems to happen More when its coming off slight boost. (about 3-5psi) but it also happens on full boost now and then.
I'm only just started running a CAI so i probably didn't hear it before.
Does any one have one of these or can someone post a link to what turbo flutter sounds like, i want to make sure is venting properly and the turbo isn't fluttering.
I have a GFB response(can go bewteen atmo and plumb back via a dial) http://www.gfb.com.au/products?page=sho ... ory_id=445
I have it set to about half as tight as it can go and fully plumb back (no vent to atmo), i had it much tighter but have taken off 4 full turns of screw.
