I need to hear the best available information for my situation. After my 99 2500 5.9 was prematurely retired by a carload of illegal immigrants I replaced it with an 09 2500 6.7. My wife and I are semi retired and just purchased a new just under 17000# loaded fifth wheel camper to travel with. I have an issue with the truck which is an ongoing problem with the O2 sensors in the exhaust. I have replaced them, occasionally cleaned and replaced them etc to no avail the codes keep coming back later. With the addition of the new camper I am considering a programmer upgrade for additional power, electronic gauges and to possibly delete the problem causing sensors. I remember researching the H & S products and Smarty. I realize this is subjective and don't want to start a war between the masses but I simply want to hear what can be done to make pulling our camper better. I am not looking to have the most Hp or the fastest truck on the highway just a strong pulling fuel efficient daily driver without sensor issues. We like our truck and would like to make it better. Thanks for your information and help.
