first i would like to say, the packaging was great. most packages i have received were bubble rapped and thrown into a box that was once for a set of scion head lights. I ordered from a place out of pa, i received the package the next day using there free shipping promo. When i opened the box, there it was shining away untouched and unopened. when pulled the waste gate out it seemed to be well constructed. i will be installing it tomorrow, i will post a update once its installed. heres some pics.

When I say 2 psi on top basically it means I'm back feeding pressure to the top of the wg pushing the spring back down causing the wg to require 4 psi to fully open again. 10 psi spring plus 2 psi coming in from the top port pushing the spring down. Now I know what you're thinking 10+2=12. Well when you press the spring back down with 2 psi it requires 2 to Mach then 2 to over come. Conclusion.. 14 psi. Here's a Diagram.

what the hell. why are you over engineering this? how do you plan to carefully meter 2psi?

I know how boost controllers work. I asked what spring you were going to run and you got convoluted.

So you're going to run a 10psi spring and a boost controller. Got it. JC
