Check this intercooler out...
Today I finally had the chance to give it a good whirl ( First time driving on a dry road in 2 WEEKS! I hate how much it rains here...anyways... ). On a good run from about 10mph to 100mph ( 1st, 2nd, and top of 3rd on my 5AT ) my IAT's went up 41* ( from 95* to 136* ) and my peak boost was 13psi ( up from 12* I saw right before I switched intercoolers ).
From the looks of it, the cooling part is better than before with instant recovery ( the other intercooler would heat soak pretty bad ) and I saw a 1psi gain in boost.
Guess it's time to dyno it. I can't believe this $170 intercooler ( $125 after a refund from the seller due to his mistake on sending me the wrong one ) is apparently not bad at all.

I wouldnt assume this is better my friend! Your seeing the benefits of having more mass of aluminum and its ability to dissipate heat.But it doesnt mean the intercooler is better.It just means it is a good heat sink! And an increase of boost is telling me that this intercooler is not working as well as it should and more then likely..... you are seeing increased boost from the lack of internal fins which normally slows down airflow and provides cooling. As air cools, pressure drops. This means that you would normally make less boost because the air is cooler and more dense with a better intercooler.

Same temps + more boost should equal more power.
Now, If I was seeing higher temps than before plus more boost than what your saying would make sense.
I see it this way. More aluminum and more mass means more cooling, while few internal fins means less restriction ( the reason why boost could go up could also be due to less restriction ). I am wrong here?

But the temps are the same ( if not better ) as before, so this cannot be the case...can it?

Correct, but could I assume that if temps stay the same and boost goes up then so does power? The car feels pretty freaking awesome...but it could be placebo...lol.
more on what quamen was saying:
The internal fins are highly necessary as it drastically increases the surface area for which the hot air comes in contact with......thereby allowing for a greater area for heat to transfer from the hot "forced inductions" air into the aluminum heat exchanger (in this case an air to air intercooler). the external fins act as heat sinks to pull heat away from the internal air passages....and those external fins are cooled by ambient air passing through the external fins as the intercooler (and car) moves through the air.

And the thing that has to be taken into consideration is what happens after run 1, run 2 and then run 3. I suspect the cooling will be greatly diminished on run 3 vs. run 1.
From the looks of it, the cooling part is better than before with instant recovery ( the other intercooler would heat soak pretty bad ) and I saw a 1psi gain in boost.
I'm gonna see if I can dyno soon.
Results are in...and they are surprising no doubt.
I gained 35whp and 43wtrq by just swapping out the intercooler. I changed nothing else!
