I4.2L vs. I4.2L

What caused the change from 270HP to 275HP? I noticed that from 2003 it's labeled 275HP.

I noticed that my father's new 2005 and my new 2005 sound louder than his older 2002, so maybe they added a less restrictive exhaust to get the extra 5 ponies.

Software; maybe a faster processor? My guess is they tightened up the control loop and are just getting better power out of the same hardware.
