I'll jump in, and I am sure others with more knowledge will follow. My perspective is the intercooler is beneficial only in that it cools the air so you can pack a denser mixture in, and so you can keep the cylinders from overheating. You do not mention what boost you are running. If you are running .8 or .9 boost, for example, I would think you are fine with what you have. I would guess the HP gain from a larger intercooler would be small.

If you are running higher boost or have other tuning that puts your engine closer to the edge in terms of being able to manage heat, then I would think a larger intercooler and some sort of meth/water injection would be worth looking into.
