My blow off valve is open almost all the time, unless I really am into the throttle. Lite cruising it's fluttering, once it hits 3500+ it's really dumping out when I'm in the throttle and climbing in rpm, like anything less than 80% throttle input it is wide open, any thoughts? Test pipes and 9 lb pulley so I'm not running as much boost as most, should my spring be stronger than the 1.5? Seems to run fine other than jerking on the highway because the valve keeps fluttering
