Since you don't seem to get any replys to this...
I've NOT fitted a Dawes Dual Stage boost controller, but a Turbosmart one. The fitting is VERY easy, it's very easy to use, and there is no bost spike worth mentioning, even when -20 degrees C the boost spike is less than 1PSI...

I am fitting my turbosmart dual controller tommorrow where did you locate the t piece off the controller. Which pipe was it the one from the turbo nipple .
Does this still keep the factory boost cut in place i want to retain this for precaution
Cheers

Lumby,
> ...was it the one from the turbo nipple...
Yes, keep the hose as short as possible
> Does this still keep the factory boost cut in place
Yes, it only replaces the factory boost solenoid
I also have a bleed hole between the T-piece and the wastegate controller, thought it was needed to ensure the wastegate could close between shifts... not sure about it though, I mean there could be something in the Turbosmart controller for this too... comments anyone?

I fitted the controller yesterday and even without switching the valve on from inside the car the boost it already up on standard, I suspect its something to do with the length of the hose .Its about 0.2bar up .
How does the length of the hose alter the boost ?
I think I will have to take it to a garage to set up correctly

Which controller do you have, does it have one or two Boost Dials to adjust the pressure with?
In case it's the one with only one dial, you should have the OEM controller connected, but I don't know exactly how, since I have the other controller. In case you also have the one with two Dials, you should leave the OEM boost solenoid out of the game. You should put the T-piece in the line from the turbo nipple and after the nipple the line should be attached to the wastegate actuator. As said before, I made a small hole in that part of the hose, don't know yet if it's needed though. The total length of the hose (from the turbo nipple to the nipple of the wastegate actuator) is between 30-40cm. The shorter the hose is, the better the boost can be controlled, i.e. less boost spike.
You say your boost rised, hmm... if you followed the instructions that cannot be the case. On the other hand, if you have left the original controller connected it of course COULD be that the T-piece causes the boost to rise...

This is what it says in the instructions:
IMPORTANT NOTES ON FITTING YOUR DS GBCV
- Turbosmart recommends that your DS GBCV is fitted by an appropriately qualified technician
- Use only Silicon hose when fitting the DS GBCV – other hoses will be effected by heat and will eventually crack or split, this will cause over-boosting and may
cause serious engine damage
- Ensure that the hose is clean and free of debris
- Ensure that all hose connections are secured with hose clamps
- Mount the DS GBCV tee piece between the pressure source and the wastegate actuator – keep the joining hoses to a minimum length
- The DS GBCV should be adequately shielded from heat and positioned at least 100mm from the turbine housing or the exhaust manifold
- A Turbosmart Fuel Cut Defender may need to be used in conjunction with your DS GBCV – refer to www.turbosmart.com.au for more detail

Yes that makes sence, a bit of a shame since that's not what you were after I guess. Now you need to set the high boost setting at another +0.2bar... ;-) The next thing you're going for is a Fuel Cut Defender/Lifter...
> Overrall a nice bit of kit for the price
Yes, I'm very impressed, and so was the guy at the local workshop, he said that it holds the boost very steady.
I'm gonna send Turbosmart an email and ask them if the bleed (after the T-piece) is needed, I'll let you know if I get an answer.
