Does anyone have instructions how to adjust the AgencyPower single BOV? How hard should the spring be set? I assume that the large cap should be taken off to have it 50/50?

Thanks

 

yeah and it will make a cool sound when letting off from full throttle or in between shifts.
it does go in sideways not vertical... make sure you know which way it goes!!!
As for the spring when its loose it will loose boost... I used my boost controller to let me know if I was losing boost or choking the car.. played around with it.. I used basically my butt dyno to adjust it. You'll hear it loosing boost off.
