I was just wondering if getting a bigger intercooler will add hp since it's gonna help bring in more cold air?
do I need to dyno tune it?
thanks!

Yes, it will give you more power. An intercooler doesn't bring in cold air though, it's cools the air that is incredibly hot after the turbo.
No dyno tuning is necessary but to get the most from it you would want a "canned tune." The forum vendors each offer their own tune and they all seem to be pretty comparable to me. There is the BSR tune from Hahn, RPi has a tune, and there is the Westers tune from Dejon (I think).
I personally think I am going to go with the Hahn intercooler and tune, with an RPi exhaust, but I am not 100% yet.
