Should I just run a Cobalt map sensor for now in my truck manifold? It will map to 14 + lbs and my wastegate spring is 10 lbs for now but I will be adding the 2nd spring once I work the bugs out of the car. I was also wondering if I added a small shot of NOS on it will the Holley Hp and the Cobalt map sensor handle it? Im very new at all this and im old school that had bbc's all my life. Thanks 
I sold it and did not like the way it fit in the intake. Maybe im wrong and im sure its been used a 1000 times but not me. Im just wondering another alternative ....Cobalt 2 bar that would fit my truck intake I guess. I read that the Duramax has a muddy resolution and not to use it. Im just open for options and if I have to plug the map hole and mount it somewhere but I have enough spaghetti all over my engine as it is.
