today i fired up my car and took it out on the streets boostin' away. last season my HKS SSQV worked just fine, and today it seemed to be struggling to open to the second stage. the screw has not been touched from last season when it worked well. is there any sort of maintenance for these things, like lubricating moving parts inside? i am starting to wonder if something is sticking inside the unit. it hasn't been used all winter pretty much. i backed the screw off to the point that it fluttered from just revving it, and even still it wouldn't make the high-pitched piercing blow off that it's supposed to, even with 6 pounds or so. any ideas as to why it's not working the way it should?
