After spending $$ and time to remove your obstructions, I can see why
you are surprised when you get no noticible difference on the dyno. :)

As long as you don't have to modify your injection system, an increase
in boost, as long as the engine not knock, is the best solution.

If you don't have an intercooler, installing one will give you approx.
20% more torque on medium rpm (without increasing the boost), because
cooling down the air with about 50'C will give you 20 % more air.
The maximum hp you get may not be much higher than before because
your injection system may allow any more fuel (max) than before to be
delivered to the engine. 

The torque increase on low and medium rpm is much more important than
an actuel hp increase, since most of the time, you don't drive with
6000 rpm but only 2000 - 4500 rpm. The car at least will feel much
mutch more resposive.
