N14 370E Celect Plus HP Question

Hi everyone,

I recently bought a an International 9700 with a Cummins N14 370E Celect Plus coupled to a Rockwell 9 speed tranny. The engine details are as follows from Cummins Quickserve:

Marketing Model Name N14-370E PLUS
Service Model Name N14 CELECT PLUS
Build Date 04 Dec 1995
CPL # CPL2027

Now my question is - is it possible to increase hp on this engine? If so - up to how much ?

Thank you.
