Performance and Ease Is Very Impressive

2007 Cat C15

After installing the AirDog on my C15, the last 7,022 mile trip was an average of 6.02 and I have seen 7.34 on a 3,601 mile run. Sometimes I think I should stop and pull the hood to see if it is really a Cat Bridge Engine in my KW! The performance and ease is very impressive when pulling the hills.
