Torque vs. Horsepower
My '06 Beaver Patriot Thunder has a C-13 Cat rated at 525hp. The guy parked next to me last week had a similar size MH (looked like a Prevost but wasn't). It also had a Cat C-13 but it was rated at 47...

Nobody mentions that Cat 'gives' the power it thinks the chassis can cool,the better they think the cooling system is the higher they will set the power.
Check out marine installations ,much much higher power and boats are always going uphill.
Common across the industry. Same goes for Cummins. In marine applications where cooling capacity is infinite and engine load is much more constant, AND emission standards are lower, indeed power is higher than in on-highway applications.
OK the OP asked if the power can be changed ?He was comparing his installation to another different builder ,its possible his at the limit for his chassis and the other has a higher capacity cooling system?
apples and oranges but still fruit ?
Absolutely. Cooling system, transmission, etc could certainly be different. And, different year models of the same engine (but with different emission specs) can and are often different.
Since this is a Caterpillar, I would start with a call to Caterpillar (877 777-3126) with the engine serial number. They can tell you exactly what HP your engine made on the dyno before leaving the Caterpillar factory. Not just what is SHOULD make, but what it actually made.
They can also tell you if an upgrade is possible.
Be sure to ask if it changes torque and HP at "normal RPM"-- many higher-HP engines only make the additional power way up in the RPM range.
