Help : MAC boost controller solenoid on M400

Guys...
I have wired the MAC valve onto my M400 with one wire from the boost solenoid to 12v switch and another one goes to AUX4 on M400.
The way I plumbed the valve is with port 3 vented to atmosphere..
Can anyone help me with the setting in Motec? We can't seem to get the boost over 7psi.. not sure what the problem is.
We have the settings set as
31hz,
0,
0
Anyhelp will be very very appreciated!
Cheers
Andy
