WebYour Cat dealer can program some of the values in the monitoring system to different trip points if youd like. I only get 12psi to 15 psi of manifold pressure now. Of course, boost pressure is a function of engine load. To add another data point to your original question about boost - our C12 typically generates 22 psi boost under full load-full speed conditions. As kind of an experiment I turned the MP-8 on and boost hit 31 - it dropped two gears but when it shifted back into 5th the alarm and check engine light came on.
