Check the ceramic insulator- if it is at all brown at the joint at the wrench lug replace them. Gap as standard.

That is correct, so how can changing the pulley change torque more than hp? They are mathematically related numbers.

As someone else mentioned, the reason the peak torque can change more than the peak HP is they occur at different rpm. If you were to check the increase in HP at the same rpm as the quoted increase in torque, you'd get the same %. Or vice versa.
In fact a better way to quantify the gains in power would be to state something along the lines of "the torque is increased 10% over the range of 2500-5000rpm" or whatever the values are.
A trivial sidenote: Contrary to popular belief, dynos don't measure HP (they measure torque).

Hold the flamethrowers for a minute... what I mean is, the peak numbers do not tell the whole story. They are simply two points on the curve. Bragging rights. The shape of the curve(s) is more important than the absolute peak value(s)...

I personally put more weight into HP numbers because they take into account the benefits of higher RPM's.
It's not the peak numbers that are the most important. The most important thing is the AREA underneath the graph.
