So i got some goodies in today, among which was said tuner, I have a full take of 87 so I loaded up the 87 perf tune. Anyways my range usually reads somewhere around 250 or so miles and now i've burned off about a 1/4 of a tank and its reading like 380 miles. Something wrong with it? Why's it displaying such a high range? and should I see about trying to fix something?
