im getting ready to upgrade my mass air w/ a 75mm Pro-m for 30lbs., so i figured id throw on a trueflow pipe from c&l. im already running a 75mm accufab tb, and wanted to know if i should finish it off by running my filter into the fenderwell of just leave it with the stock setup? also since the stock intake with out the silencer is considered a cai, should i get the mass air thats programmed for the cold air?

I don't think I would consider the stock intake without the silencer a "cold air" intake setup. In the stock location with the silencer removed you are stuck with the air from the engine bay which will be an easy 50 degrees hotter than the ambient air. If you are able to, it is highly desirable to isolate the intake from the heat in the engine bay.
The stock air box pulls air from inside the fenderwell - not from the engine bay....
BUT - a conical filter will give you more air-flow than the stock-style flat panel filter, and you SHOULD put the conical filter in the fenderwell instead of inside the engine bay.
If you upgrade the MAF and TB, you might as well upgrade the whole intake path, because the stock rubber tube and panel filter aren't the greatest for moving large volumes of air.

The problem with the true fenderwell CAI is that the MAF meter is left to try and meter turbulent air coming out of the curved tube that connects it to the filter in the fernerwell. This often results in inconsistent signal and poor operation. I believe the Pro-M "cold air" unit comes with a screen that attaches to the inlet of the meter and smooths airflow for better readings.
Actually, just read this. They explain it best.

what about the tru-flow pipe? i read that the plastic is better with keeping the cooler than the metal piping due to the fact that the metal can absorb much more heat. I figured what i would do is keep the stock airbox and just cut the inlet to the box enough to run an elbow through it and into the fenderwell since i cant find one of those fancy metal heat shields.
You're confusing the silencer with the air box (or maybe just unfamiliar with the fox body?). The silencer (on a fox) is a completely separate piece that's located entirely inside the fenderwell, directly opposite the airbox - you can't see it from the engine bay. Even without the silencer, the opening for the airbox is sealed against the fenderwell.
The part he's holding in his hand is the air silencer. The airbox still seals against that opening to the fenderwell.

I have been working on motorcycles for a while and what those engines want in an airbox is a large pool of still air for the engine to draw from. The bigger the air box the better and I'm sure the same holds true here.
I would think the best split-the-difference system would be the conical filter and large air box from a ram-air kit. Throw the vaccuum scoop and hose away and keep the rest. It will bolt right in and look trick enough while still housing a large conical air filter drawing cold air from the fender area.
