Has anyone had/heard any good experiences with one? I've been looking around for something that will work well for a car that doesnt have a air mass meter like the rest of the cars do.. The one im looking at is adjustable, works like BOV and a CBV at the same time:

"stealth fx"

side note: yeah, my cars got some 20 year old technology called a bosch k-jetronic injection... basically like cross between carbs and electronic, a normal BOV will work, but will dump fuel like mad possibly causing backfires
