Hi guys,
I have a custom intake on my 250 and the sound of the spool and dose was always quite evident but aftergetting the superchips Bluefin stg1 tune I decided it was worth installing a tunable recirc valve.
I fitted the Forge recirc valve with the yellow spring as its rated to 15-25psi but rather than the standard 'chhhhhh' sound when dosing its a broken 'ch-ch-ch' sound which leads me to believe that perhaps the air isnt escaping fully through the valve and rather being forced back through the turbo which is bad.
Has anyone else fitted the yellow spring after a stg1 tune and getting a similar sound? And am I correct in assuming this sound is boost reflux back through the turbo?
