Here are the UOA results from my parents' 2004 Monaco Dynasty coach.

The back story is here: BITOG thread

It is a 2004 Cummins ISL, not ISM, and it is the 330 hp version. In 2005, dad discovered a large air filter leak, with a lot of dust noted in the intake area. This was corrected at 43,000 miles (unknown how long it was like that). The engine was dyno'd at that time and put 291 hp to the wheels. The engine was dyno'd again in 2007 and put 293 hp to the wheels. Here are the UOAs, all done at various SpeedCo locations across the country.

Any and all thoughts and comments are appreciated.
