I'm going to be purchasing an X4 tuner from 5-star but not sure which tunes I should get. I was thinking Performance, Daily Street and Towing all in 91 Octane. Any recommendations? I don't have anything done to my truck yet, as far as performance mods. I will have a cold air intake in the near future and can then have the tunes modified, if need be. My truck really won't be towing anything to the maximum weight. We have a diesel to tow our toy hauler. Maybe occasionally our 16' V-nose enclosed trailer. Feedback would be greatly appreciated before I pull the trigger. Thanks guys!
