this is wrong. Take it BEFORE the throttle body not after it.
Sorry Nick, but I respectfully disagree here. Firstly, as has been mentioned, it's a diesel so there is no throttle body. Secondly, even if there is, what's the point in measuring before the throttle body? At partial throttle you'll have a reasonable pressure drop across the throttle (it is, afterall, a throttle!).
Of course it all depends what you want your boost gauge to tell you, if you want to know how much pressure is in your intercooler piping then certainly, go before the throttle, but if you want to know how much pressure is going into your engine, then go after the throttle body.
My bad... so used to petrol setup's (that's all i ever touch)
