Why would you put a different cam in and NOT tune it? Sounds like a recipe for disaster. I can see trying to get as much as possible without a tune, with just boltons. Once you break into the engine, you REALLY need to tune it. If not for the sake of optimizing your setup, then for the safety of your engine.
