I just got my Forge MBC in the mail and had a question. It didn't have any instructions and their website had zilch info. It came with an extra spring. Would this just be a replacement spring or is it like a low boost/ high boost deal?

With the MBC installed properly, the lowest I can set the boost is 12 psi. I was hoping to leave it at 10 until I can get my wideband installed to make sure my afr is good.

Anyone with this boost controller know which spring is which?
