Anyone else have this happen? I received my tuner from Bama (awesome tune btw).

After the tune was complete, on a 3/4 of a full tank, I saw my "miles until empty go up from around 200 miles, to about 275 miles. Now I know this tune may help with efficiency, but that is a little extreme.

To make matter worse, my MPG is not really significantly higher, so I hav eno idea why the car is registering my tank is 75 miles fuller than it was before.

I just filled up the tank to see if it would reset back to normal, and now that I have a full tank, it shows 330 miles until empty. Typically, it shows 270-280 miles.

What gives? I'm not getting such an increase in MPG, so why is it telling me I have more miles until empty?

A few people on here have claimed that even when it says 0 miles til empty they can go quite a few miles, perhaps done by Ford to make sure you don't run out of gas. Maybe the tune gets rid of that threshold and you see an actual estimate.

The same thing happens when you unplug your battery and hook it back up. It has to relearn all the fuel trim strategies for your driving habits and idle. It did not turn your stang into a gas sipping yaris. You may benefit another 1-2mpg possibly but that will fade away due to it being more fun to drive. Watch how quickly your miles to empty drops on this tank.

16 gal tank divided by +60 miles = +3.75 miles/gallon. Sure it's not just benefits of the tune?
according to the mpg gained after the tune, I'm at most 1mpg over what I was getting before.

Well, my first tank did not dip at all. I was almost on empty and it said I have 100 miles left. I knew it was wrong.

I hoped a refill would correct the issue. It didn't.

Right after any tune, the computer will have to relearn how far you drive on a tank. So until it does, it defaults to 200+.

With my tune, my mpg is probably a bit worse city only driving then before... Depending on how aggressive I drive. But even driving super conservative, it is 1 mpg less than before. Again, all city driving. That is using the 93 race all the time.

Hey,

Smozilla said it correct! This is your system relearning your fuel trims and strategies etc... Give it a tank or two and it should be ready to go. If you're still having the same occurrence give my Bama team a call and they'll look into your file for you!

I'm glad to hear you're enjoying our tune though! Thanks for the props we really appreciate it.

Our Bama Performance tuning specialists are here in the building Monday-Friday from 9AM-5:30PM EST and Saturday 9AM-5:30PM EST. You can hit them up directly at 888.226.9764 and they'll get you squared away!

My bad, I was wrong. I was thinking about my wife's truck, it is 16.5 and I confused the two. My mistake. I have been thinking we were at .5 for so long, that puts most of my calculations off a bit ...
lol...no biggie. I wasn't trying to be an ass with that comment.

Could be worse, first month I had the car I thought it was a 19 gallon tank. I DK where I got that idea from, probably one of the many other cars I was debating between. Started driving her and based on doing some math in my head I was like, "wow this comp isn't even close, no way am I getting 16mpg with this car!

haha :)

Didn't take it rude, I just try to man up and say I am wrong when I am wrong. Often people just avoid it or make an excuse, and well, I was wrong lol.

I always just do mileage times .027 plus mileage divided by fuel put in for my mpg. Just had a 400+ mile trip, should be around 35 mpg for it. The hills of PA killed my mileage.

Well I just tuned mine and I get 330 on a full tank
Your still on relearn process, once your new tune adjusts to good driving habits, it will change... Most spirited drivers like me will probably get 180-200 miles to empty on average
