Very nice you can add E85 sensor for around 50 bucks and have your tuner unlock it. You would be around 420!!!

I got lucky, I live out in the country and the closet gas station to my house has it. Then the one right by my work in the city got it too. But I don't want to think about how bad the gas mileage will be when I start pulling my wakeboat this spring.

do u run 93?

Premium 93 here is 2.99. E85 is like 1.75 or something like that. It only takes 45-49 bucks to fill up.

Here with our altitude we only need/have premium 91. And no, I run 87 daily. its about $2.79-3.69/gal. Premium is about $0.30/gal more.
When I go on a trip or plan on doing anything fun I'll get 91 but my normal driving I save the little bit of cash. I know people will prob give me crap but I do a fair amount of driving. I've had my truck about 8 months and close to 23,000 miles so it adds up faster than you'd think.

Exactly!! Lol
I'm normally pretty light footed and a decent amount of highway. I normally get 19-20 mpg if that tells anything.

A little video from earlier. Warm start and easy take off. I'll get a cold start and harder take off this weekend.
