Dawes valve set up

[mudski]

The vacuum solenoid on the patrols is a two stage set up, three ports. It controls boost and spool up rate, one port for vacuum supply, the other two for max boost and spool up rate, if you want to call it that. Just about every other car I have seen, Triton, Ranger and Navara, with the VNT turbo it only has a single stage solenoid, two ports, supply and delivery to the turbo. One line in from the pump and one line out to the turbo. In this case you do completely by pass the solenoid.
In your case you cant. The solenoid still relies on the "bleed port", the third port on the solenoid which goes to the air resonator box, to let some of the vacuum pressure in and out to control the spool up rate. Using a needle valve in replace of the third port to control the "vacuum bleed" takes away the final control of the vacuum solenoid.
You still can do what you have done, but obviously the ECU is designed differently to the other vehicles and is designed for the three ports. So the way you have done it you have no control on spool up rate and you wont be getting the right performance out of your ride.
If you want to continue to not use a needle valve I would be putting the vacuum supply back onto the end port of the solenoid, the middle port to the Dawes and the inner port to the air resonator box. That is how it is done when NOT using a needle valve.

Edit : I just looked at the link the OP supplied. Going by their description it would be for the single stage solenoid setup, like a Triton. Love their price too. lol.
Edit 2 : Just my personal opinion here and only going by my own experience from fitting these to numerous CRD's now. Not fitting the needle valve is only doing half the job. Mechanics say you don't "need" a needle valve. Well, you don't need the dawes either. You are only modifying your car to make it run better and smoother. It is proven that the needle valve, when used with a Dawes, makes the setup a crap load better, same as adjusting the VNT screw. People go to amazing lengths and install big exhausts, chips, bigger and better air intakes etc etc. It takes a whole 10 minutes to instal. So why wouldn't you put one in?
