I dd on 85 with over 3k miles on it with 0 issues so far.

I average 23.x mpg (lots of highway but still spirited driving).

How easy is it to go back and forth with a proper tune? Like if I want to drive harder with better performance, can I use it one week with an e85 tune, and then the next week just switch to like 91 if I want better gas mileage for say a road trip?

i dont own a tune yet, But its really simple, You just have to drain your tank and switch maps.

I'll just drive to the gas station while my low fuel light is on, and keep the revs at 4k until it runs out

You would think flex fuel would be standard on our cars since it post such great gains!!!??

You just have to get a Flex Fuel Kit with your E85 tune.. then you won't have to worry about draining your 93 gas tank empty before filling up with E85.

I have Visconti's e85 tune and have been on e85 since October. I did switch to pump gas for 2 weeks in December because of cold start issues but the cold start issues have now been resolved. Car fires up just like pump gas. I only get around 17mpg but it's well worth it because the car feels like a little beast for being n/a especially on the latest updated tune

Geez, that much of a gas mileage hit?

Area86 · 03-11-2013, 02:16 AM

Yeah but I was only getting around 24-25 on pump. Mostly city driving for me.

You can probably expect about a 28% decrease in fuel economy as a rough estimate. That is considering you drive exactly the same, but its probably going to be more of a hit initially because having that much more power is going to be too much fun for most to ignore.

i think e85 gives you another 30 wheel right?
