Do you have a MH with a Banks Kit or just asking? The Banks kit is an Engineered Product that is designed to increase the Horsepower Output within safe limits of the engine design.
The Boost Gauge monitors Turbocharger Boost Pressure which is an indication of the amount of air being forced into the engine by the Turbocharger. 25-26 Psi is the high limit. Boost Pressure is controlled by a Waste Gate. Driver does not have control of this function other than to ease off on the throttle and shift to a lower gear.
Temperature Gauge is reading Exhaust Temperature in the Exhaust Manifold before it enters the Turbocharger. Upper limit is 1300 Degrees F and is limited by the Fuel Injection Pump Delivery. Exhaust Temp is a number you should pay attention to when climbing hills. If it attempts to exceed 1300 Deg., you need to back off on the throttle and shift to a lower gear.
Exhaust temps in excess of 1300 Deg. Will result in catastrophic internal engine damage.
By design, the Banks Kit will control these parameters but provides these two gauges to enable the driver to monitor the engine performance should a problem develop.
