Specification:

Dawes valve, needle valve and EGR plate kit

All Dawes valves come fitted with the heavy duty spring and lock nut

An instrument needle valve uses a tapered pin to gradually open a space for fine control of flow. The flow can be controlled and regulated with the use of a spindle. A needle valve has a relatively small orifice with a long, tapered seat, and a needle-shaped plunger on the end of a screw, which exactly fits the seat.
Needle valves are usually used in flow-metering applications, especially when a constant, calibrated, low flow rate must be maintained for some time, such as the idle fuel flow in a carburettor. 

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.

After some testing and tuning shows taht the engine running  nicely indeed. At around 100kph the boost sits between 11-12 psi and under gentle load its about 14.5psi. If floor it the boost gets up to the 15.5-15.9psi
the Patrol has ever run. Plenty of power yet very smooth as the boost is linear and matches the amount of fuel being added to the engine.
