Default new turbo boost problems

hi there i have just fitted a new turbotechnics standard turbo to my escort and the boost did not kick in it was like it was just going throught the wastgate. so i adjusted the atuator by screwing it in till i had about 4mm pre load and gave it a spin and it works but i only get 0.2 bar i have a bleed valve fitted and that has not made any differance you can here the turbo spooling up tilll it get s to 0.2 bar then the wastegate opens. i have got a 31 atuator which was on the old turbo which was running 10-15 fine do you think i aught to put a bigger atuator on it i only want to run about 10 psi, its on an 1.8 zvh engine. the other thing is it has a uprated cam in and the top end it a bit noisey sound like a diesel but when you rev it it is much quiter. so i have tried to do the timing i dont know what the timing is for a zvh but i put the crank putty TDC and adjusted the cam to about 10 or 12 on the adjustable pully have got a timimg light but i dont really know what i am doing as far as adjusting the engine as i can adjust the top pully and the dizzy any help would be good thanks rob.
