The dealership where I bought my LMM said that he would sell me a PPE. Would this really help my fuel mileage, I pull a 16ft landscaping trailer daily, and I need some help QUICK to get some better MPG!I dont need any more power, these LMMs are strong! I am gonna keep this truck until it wont pull another day, I dont want to put anything on here thats going to hurt the engine, trans ect..Also, if my truck ever had any warranty recalls,repairs ect, would they be able to tell that I had a box on it? Seriously men, I need better fuel mileage, what I have heard, some of these programmers,downloaders ect, will only help MPG MAYBE 2 mpg,is that true? Thanks in advance for all of your help! ALL INPUT GREATLY APPRECEIATED!!!!!!!!!!!!!!!!!!!!!!!!! Jim B
