My setup is that my boost gauge is tee'd off of a vacuum line on the top of the throttle body. This way, it tells me what my engine is seeing, not what my turbo is pushing. My boost controller however basically intercepts a line that goes from my hotpipe to the wastegate controller. Where you install yours is basically how you want to read pressure and what the controller thinks your boosting at. If you install it as close to the turbo as possible, then you will get the pressure your turbo is putting out, but not the pressure that your engine is actually seeing. The best setup IMO is to have two boost gauges, lol. Have the controller and a boost gauge at the turbo side, and another gauge at the intake manifold side. That way you can make sure you don't overboost your turbo, but also know exactly how much pressure loss you are getting throughout your IC plumbing. Hope this all makes sense, lol. Sounds like I'm rambling!
