Anyone know were I can purchase a boost pressure sensor ?
I need a sensor that will only give an output voltage under boost and no output under vacuum.

I saw some at www.mcmaster.com It is an industrial supply house. You may want to get an adjustable one.

did you find what you were looking for tom? ive tried to find one myself i would like to manipulate voltages on my turbo 4.7 i thought about using a chrysler turbo map sensore piggy backed to my existing one. i also thought of moving the throttle body to the intake side of the turbo, but after looking at the boost guage while running it seems the vacuum drops under acceleration without the turbo creating boost (i.e. i unhooked the intake tube and ran it)so im not sure what direction to go any clues? voltage or no voltage at acceleration?

azdak,
I decided to add a 2 bar map sensor as my boost indicator to the smt6 piggy-back computer.
I connected a bleeder valve to the existing map sensor so it wouldnt see any boost, just vacumn.
A normal map sensor reacts to both boost and vacumn the same. ie. 9lbs boost will give the same voltage as 20 inHg vacumn, so under boost the ECU thinks it's running with max vacumn.
Hope this helps.

2 bar MAP sensor hooked up to the stock PCM with a proper remap is the way to do it.

azdak, what exactly are you trying to do ?
My wiring diagram (97 dakota 5.2L) may be completely different from yours.
I am using the stock map to the ECU and the 2 Bar map goes to a SMT6 piggy-back controller.
