Is there a reason to go below 17psi? If your have everything installed properly and the minimum is 17psi, then that is not the soft spring. The soft spring set to minimum will give you wastegate pressure, which is 11psi. The stiff spring will start up around 17psi, so maybe you have them backwards. If the boost won't go up or down, then it's not installed properly, or the spring is not seated on the nipple inside the MBC.

I will double check it today. The only reason I would go below 17psi would be because I am having some major misfire issues that i am trying to sort out when I go over 17psi.

Thanks!

Regardless of which one comes pre-installed in your unit (depending on where you purchase it from [we pre-build them with the softer of the two installed]), there should be two springs included with EVERY unit to allow for a wide range of adjustability.
If you do not have two springs, give us a call and we'll be sure that you get the additional one that you need.

I'm not 100% sure that I didn't get the spring - I'm at my gf's house - I'll check when I get home.
Now I'm not so sure... LOL. I bought a lot of stuff, but don't seem to recall that I had one.
I'll be sure to give you a call if I need one.
Thanks for the reply and offer of the missing spring.

Well, the springs changed or the units changed. Back when I got mine, the soft spring couldn't go over 19psi, so we all had to use the stiff spring. Then, a later shipment was causing problems, because people would immediately put in the stiff spring but couldn't turn the boost down any lower than 24-25psi, and their soft spring could go above 19psi easily. The key is to start with the soft spring and turn it up to see if it goes over 20psi. If not, then put in the stiff spring.
