Drive pressure goes into your exhaust maniflod just like a pyro. It measures the pressure in your exhaust manifold. If your turbo is not spooled up your drive pressure will be high. You want your drive pressure to be low. The lower the pressure the better the exhaust is moving through your turbo and out the exhaust.
