I have an 04 3500 c/c duramax. I was wondering what kind of performance enhancement that is available that would work while i pull my 14k 5th wheel. It has to be easy to install,not need any gauges to monitor, and if possible get better fuel milage! Not looking for big HP just a little more if you know what i mean. Is there such a thing?
