I read the whole articl when it was released... and now I cannot as I'm not a subscriber.
This article is good and describes how to build a DIY Boost Control.
It will also explain why you do this!

Basically it stops wastgate creep or a weak wastgate.
As the boost starts to increase as you put the pedal to the metal... a weak wastgate will start to open and release pressure and that means a loss of boost pressure and an under-performance in the turbo system.
What this system has is 2 things... MIN and MAX pressure Valves that you can DIAL into a specified pressure.
The MIN pressure valve will not open up untill a Dailed up pressure is rerached - Thats is when the wastegate is gonna start to open.
The MAX pressure valve is used to stop OVER boost pressure blowing you turbo system up!
So if you have a subscription to AutoSpeed.com.au online Mag... Please share!
