The higher the RPM, the more positive boost it takes to close the bypass. While in theory, this makes sense, from what I have read it means that I need a stronger spring on my bypass valve to keep it closed under those situations. As I understand it, the bypass should only open when I am not on the throttle at all.

Can someone help me out here? Anyone else with this situation? Is the spring even upgradable or do I need a new bypass?

Here is a partial throttle video where you can hear the hissing of the bypass:

Mine had the same hiss actually. We initially thought it was a boost leak but narrowed it down to the bypass valve. I'm winding if upgrading to the metal housing unit would solve that

Care to share? In case anybody else needs it.

Service folks over there are great. CJ gets a lot of props, but Joe is great too!

They have a new billet bypass that they ship with new units - they are sending the newer part to replace the plastic bypass to see if that fixes it. I'll report back as soon as I try.

Thank you sir. Even if it doesn't work for you, it might work for others. Crossing my fingers for you though!

Nice! Make sure you do the inventory check - if you are missing something, it's early enough that they might be able to get it out today. And don't forget to clamp or zip tie those hoses as others have mentioned, otherwise good luck with the install!

@xDanger_208x still plenty early. Shoot me a PM if anything is out of place or you simply have any questions.

I should probably do the same considering everything is still in the box and I received last week.

Will the install be easier with the radiator off I'm swapping to the skunk alpha.
