Where's my boost?

Hi all,
My turbo is rather sick. It's an aftermarket Denco on a 1HZ 105 series 'cruiser. I think I've had the problem for a while as my boost has always been low at around 5 psi. Anyway, I recently fitted a Denco water to air intercooler, which came complete with a replacement high boost wastegate actuator. Flat out, can't get more than 4.5 psi boost, even with the actuator pipe disconnected.

Had the injectors done and pump checked out this week. A run on the dyno confirms my problem. Tomorrow, I will remove the turbo assembly and check it out physically to look for possible causes.

In the meantime, I wonder if anyone else here has experienced a similar issue, particularly if you have the same brand hairdryer? If so, what did you find? I have a few theories, but perhaps someone else has been there before me.

Any helpful suggestions or ideas will be gratefully accepted.

Cheers
Gerry
