Yes, I'm aware the the FMIC (the big GTM silver one in the middle) is to cool the charged air form the SC. There are sill 3 additional smaller black coolers (one center, 2 sides) and I want to know what each of them is for. I was presuming the one in the center was the AT cooler but not sure what the other 2 are for. One for engine oil. The 4th is for ?

That's not really a fair question. How do you define oil cooler efficiency? Also, there are different size oil cooler that you can choose from, 19row, 25 row, 40 row. They will have different cooling characteristics. GTM uses Setrab oil coolers. If you want all the specifications, you can find them right here:

How hot is the oil or transmission fluid expected to be depends on how you drive the car. Even my twin turboed car will have engine oil temperature like a stock G37 if I drive it normally. If I push on it, I can drive the temperature up to 260 even with an oil cooler. On the flip side, you can push a stock G37 up to 260 degrees with hard driving too.

You're missing the point. The air filters are going to be taking air from directly behind the oil cooler (or transmission cooler). If the cooler is effient and works well, that air is going to be hot. If the cooler is not that effient then why have it.

Why do you think there is an intercooler? Even if the air sucked in from the behind the oil coolers is hot, it is nothing compared to the heat the air will pick up as it travels through the supercharger and near the engine headers. The charged hot air travels through the intercooler to remove heat and then back to engine for combustion.
The air temperature that enters the intake does not have too much effect on the temperature of air that enters into the engine, as long as the intercooler is efficient.
This is why GTM designs their piping so that the MAF sensor is closest to the engine. It will accurately measure the temperature that enters the engine. This is an advantage over Stillen, who put their MAF sensor at the intake.

Good point, yet "hot" is relative.. how hot is the question.. looks like it's time to get datalogging to measure before and after temps

Now let's talk about tuning. Do you tune on the dyno, on the street, at the track? You just said the transmission and oil temps very so much depending on your driving at the time. So that tells me that cooler will sometimes be putting out hot air and sometimes it won't. How do you make an optimal tune for that? My guess is you don't, you just make something that will work.
Why you got to be like that? You know perfectly well that's not true. I ask a perfectly legitimate question about a concern I see and you call me a hater. I also posted this to bring it to your attention since it's your car. That way if you did see it as an issue it could be addressed right away. Not everyone goes around posting hate, some of us are here to learn and help.
