Suitable camshafts for ABF 16VT engine. Stock or `Turbo specific` ?

I`m currently running an ABF engine with standard ABF cams. From reading This Thread, I started wondering if it would be worth fitting a specific ABF-Turbo exhaust camshaft ?

I`m running 0.8 to 0.9 Bar peak boost. The boost control solenoid is only operating at 45% duty cycle at the moment.

Would fitting a Turbo exhaust cam, or Turbo inlet & exhaust cams give a worthwhile increase whilst still targetting 0.8-0.9 Bar boost ?

I could run higher boost than I do now, but I don`t want to

 

The cams are only part of the net sum of components that help to achieve the upper engine torque.

The wee TD04 hair drier would be the first step I would take before shelling out the retail price of 500 + vernier for a set of turbo specific cams.
