My car(my 95 wrx) is running a dawes at 1.1 bar and is very harsh to drive in traffic so I was wondering if it is possible to run 2 stage boost on my car without the ECU getting confused?
I have drawn a diagram of how I was thinking of doing this, any other suggestions would be welcome
when the bleed valve is open it will bypass the dawes letting the actuator open at around 0.5 bar boost, when it is closed the dawes will operate as normal.

I run a DIY 2 stage boost on MY96 UK.
I have a PPP ECU so standard boost is 13.6 psi.
I have a DIY FCD (cuts in around 13.5 PSI & cuts out around 18.5 PSI)
I also have a Dawes @ 17PSI.
The above too are switchable on the fly via a single in Car switch - the FCD using a relay & the Dawes using two standard 3 port solenoids.
I'm selling this kit this weekend & will eventually update my website (SEE PROFILE) to describe how it was done.
Best of luck,
Chris.
