Help first time using a tuner

Hi, I just got the sct x4 tuner for my 2017 6.7 and I’m trying to get the the best mileage I can.
1. what stock tune is best for mileage?
2. Should I look for a custom tune, if how?
3. My engine light is on now following using the street tune why is that?

thanks in advance
Tom

By a Ranger for better MPG.

I'm all about tuners, or was anyways. Best bet is to try all the tunes for better MPG. Remember, winter blend fuel will yield less miles per gallon.

Is this a delete or in place tuner, delete will improve regardless.

You should be able to read the check engine light with a turner.

Banks is better for fuel ecomony... The SCT might throw a code if your completely stock. If you are throwing more fuel at it
