First off I'm brand new to 6.4's. just picked up my first one last week. It's fully ******d and has a sct x4 tuner on it now that has Cale Thompson tunes on it. The truck runs extremely well but I hate the fact that a person has to wait 10-15 mins to change the tunes, plus I have no monitor (previous owner kept it) I bought a h&s mini maxx off a guy I work with that has the 300 hot dam tune on it. I don't race this thing and don't plan on it but I like the fact that with the h&s I change the tunes on the fly. What would you guys do? any input appreciated. Thanks gentlemen in advance
