gtz oversized boost pulley not raising boost

[RAZA]

Before anyone asks I've searched on this and found bugger all.

I've put an oversized pulley into my ae101 gtz, and found that it has made the boost increase by a pound or two, but not by the 6 or 7 pounds it was suposed to....

Is there something else one must change to alter the boost or do I have an air leak somewhere? I've checked for leaks and can't find anything so I'm hoping there is some other explaination.

If anyone knows that would be mint.

Cheers
