What is Drive Pressure???

I have been seeing alot about drive pressure recently and I was just wondering what it is, what are the causes, should I monitor it, and the effects of having to much? Sorry if this is a stupid question but I am just trying to learn as much as I can. Thanks for the info

drive pressure is the amount of pressure in the exhaust manifold, you need exhaust pressure to drive the turbine in the turbo to make boost, and you can have too much of it but it is not really something that you need to monitor.
