please help, no boost from turbo

Hi,
Having problems getting my turbo to boost after the actuator bracket broke.
I have remounted the actuator onto the reparied bracket, and adjusted the rod such that it is pulling the actuator tight ( and hopefully the wastegate closed ) . However I still get no boost until 5000 rpm plus.
I have had some help from here with understanding how the wastegate and actuator work, for which I am grateful, and I think I have mounted and adjusted it correctly.
Can anyone suggest the why the car is still not boosting. It came on boost at about 3000rpm before the bracket broke.
Cheers
Paul.

Mmmm, interesting.
I thought the actuator pulls the wastegate closed, and then when the boost gets to desired reading it open the wastegate. Is this correct ?
Are you implying that if my setup is adjusted correctly, maybe the actuator is opening too early ?
Or have I understood how it works incorrectly ??

The AMAL valve is an ecu controled electronic solinoid which operates very much in the same way as a bleed valve only the ECU has the ability to 'close the bleed' and lower the boost if required for any reason, this has 3 ports and 1 electricl connector which carries 2 wires. The AMAL valve is about 40mm round and around 20mm high and is normally mounted on top of the intercooler, it has 3 hoses going to it, 1 which goes to the air box, one which goes to the turbine housing and another which goes to the actuator.

ive seen the actualy wastegate crack inside the turbo causing it to leak and only boost when the thing is spinning like mad to over come the leak caused by the crack. u could of damaged it when it broke first time
