All the trucks have fuel plates it's just what profile they have installed. I think you mean does anyone use one other than stock for general trailer towing.... Yes a lot of folks do. I have currently a #10 and I can get my pyro over 1400 but it have to sort of want to. Now we use to pull a 31ft TT, 9200~9500lbs all over the place and I could sit the cruise at 75mph and not have to worry about her overheating on the pyro. Now if I get off my lazy butt and install the wild one that Rubberfish sent me I'm sure my results will change.
