I am thinking of getting the Intune but my fuel cost is covered by work since I use my own vehicle. We can only use regular fuel & with the cost of fuel rising every day there is no way I can slip mid-grade into my expenses. Would it still make sense to buy the Intune especially since I can't run the other tunes? I would love better fuel mileage (dreaming I know) or turning of the MDS but I don't know if just turning off MDS is worth the cost. Is the MPG tune good, does it help at all? I would rather control my fuel costs so I can keep using my truck instead of some econo box company car!
