C-12 425 HP to 455 HP.
I'm thinking about boosting my C-12 from 425 to 455 HP but wondering if it's really worth. Will I even notice a 30 HP increase. The change is simple, just stop at a CAT dealer for a program change. ...

Questions to make sure this "upgrade" is relevant to you/your coach:
Any change in torque? If so, how much and at what RPM?
Those extra HP-- are they are RPM's I normally run the engine, or only at close to governed RPM?
Is my cooling system adequate to accommodate the additional heat load. Let's face it, the time you will want those extra HP are on long, sustained grades-- just the time that your cooling system is already stressed. So, if you overheat on those conditions already, probably a bad idea. If you don't go over 200 degrees F on those long sustained climbs at high ambient temperatures, you may have the reserve to accommodate the additional heat load.
