I don't have a picture of it, but if your looking in the engine compartment there is a black rectangular box on the top of the firewall on the left hand side (passenger side) that pertrudes into the engine bay. It has a black rubber hose that comes out of it and goes down to the intake manifold, this is the MAP sensor line. Cut this line and then get an air fitting T and put it back together, running yout boost line to there. It is to the upper right of the heater box.

Like coon said, I have two T's in my line now (Overboost Annihilator, Boost Gauge) and still accurate reading's...
Just "T" the MAP sensor line and run the line through the hoses that are attached with brackets to the firewall for a good clean look and it helps keep them out of your way for further mods!

Hmmmmmmm???? This concerns me, mine is black (either that or its really dirty with some super sticky chit lol) but it still seems to work properly. Was there a recall on them or is it something that I'm going to have to fess up and buy form the stealership?

I also have the black map sensor so now i'm curious as to if I need to get it changed. Also will I get inaccurate boost readings if I just tap into my "Y" pipe. I notice I don't build much boost tell about 2000rpm. At about 2800-3000 I maxs out at 15-16 psi, does this sound right?

Those boost numbers are pretty close for a stock truck. Some say they get close to 20 or so but lots say they get about what you have. I replaced my black line with a piece of 1/4" black line again. It is thick so it can't collapse. My old black one was clean but I moved it to the hot side of spyder on my ic setup so I needed a longer one.
Have you checked all your rubber boots to make sure you have no boost leaks? Both of my original y pipe boots were leaking.

15-16 lbs would be normal if you were at a high elevation, assuming im correct on that. but if your at sea level assuming im right you will have a couple pounds higher. out here in mass with a moderatly dusted wheel i can hit 20lbs on the highway with out the chip, with the chip on thats a whole different story
where are you located? check your impellor wheel, if its rounded off at the ends then you know why your boost is lower than usual

Collapse wasnt the right word to use but I just wanted a nice solid line that couldn't crack or get damaged easy.
