Boost Gauge Install Question
Finally had my gauges installed today. I'm still very new to this, so please bear with me. Here goes; I tested on the way home and stomped on it. The boost jumped right up to 24 lbs. and stopped. I also have a boost relief valve installed in the map line. The way it is installed, the line runs from the manifold, then boost relief valve, then boost gauge, and finally map sensor. It seems to me that the boost relief valve and the T for the boost gauge are installed backwards. Should it be the other way around?
Another question. Am I going to get an accurate boost reading from the map line with the relief valve installed anywhere in that line? It seems that the valve will leak off pressure from the entire line, so that the map sensor will not detect the over boosting. If this is correct, the boost gauge will not be accurate. Is this right? Hope this makes sense to some one. Thanks!!

Yep. They are backwards...Should be boost gauge, relief valve, then map sensor. with this setup your boost gauge should read correctly since there is more pressure downstream. I have a regulator installed on mine set at 22lbs and my boost gauge will show higher than 22lbs..
