Recently acquired a Lund cam tune and the car drives flawlessly with a huge increase of power over stock, minus the MpG's. My Mpgs went from 17.5 town to 12.5 with the same style of driving. What are your Mpgs with cam tune?
I drive lots of highway mileage, but I would say mine stays around 20. Non-cammed tunes nets me about 23 average. AED tune from over a year ago, don't know if he has updated it at all.
I have not clocked mine yet, but it's very obvious that's its dumping more fuel at idle which should decrease the avg mpg's by 3-4. My guess. Now if you road trip it on the highway for the whole tank I doubt you will see that much of a decrease. City driving will definitely kill the mpgs.
