im running custom tunes on my U7130 which yours would be the U7131 which as of now has no custom tunes that i know of, im running the RKL 200HP tune that i downloaded and i have not dynoed yet me and my cousin are going to in a few months when we get some diesel events closer to us, and everyone that i have asked said it would be in the 500s, and as far as fuel mileage im getting around 18 on the highway with a heavy foot, and 13-14 around town and county roads, take into consideration i drive like a pissed off teenager so im sure you can do alot betterHey moto any idea what kinda HP your sitting at right now? Do you keep the predator on 100 or 180? How about fuel mileage with it?
Got one coming in the mail. Cant wait.
