can you guys give me a few ideas, maybe with some pics as to where you spliced the vacuum line for your boost gauge. it says any line with air, could i use the one going from near the coil that has a blue spaceship type thing on it? and before or after the blue piece?? or could i use the line that goes into my AFPR?? give me some help, i know its a dumb question but my brain is burnt and i just want this done along with my countless other things goin in the car.

 

first one, no. that blue spacer is a one way valve going to your opti. since air will only go in one direction, you will either see boost or vacuum, but not both.

the second is a yes. Any line coming out of your intake manifold without a one way check valve will work -- as long as it doesn't have a leak.
