Hey Joe, I have the RKX BOV.What BOV and how did you set it up?
I took the washers out after the ride and now I can here it open almost as soon as I let off the throttle. Code is still there, is it the 4000rpm deal to clear the code? Do I try the red spring and washers?Sounds like the BOV is not opening when you let off the throttle. This would be because of too much spring pressure. Remove the washers and try it. It needs to open (vent) as soon as you let off the throttle. The code will clear it's self once you resolve the issue.
Set it up to be normally closed and only open when you let off the throttle under boostI've been running the RKX and it's been great. The only thing I don't like is listening to it continuously vent while driving. It closes right away with throttle input and vents immediately when off the throttle. It's the constant hissing I don't like.
