I have a 2002 Ram 1500 with the 5.9L gas engine. was thinking about a programmer and am wondering if anyone thinks it might be worth getting. money is not really an issue, id just hate to waste it if its not going to really do anything. Maybe trying to get a little more power or be able to gain a little in the MPG department. Any particular one that you recommend? brand? Pros and cons? i dont want it to give me an issues down the road or anything. heard of them throwing the engine light on and codes? not sure. thanks for your advice!
