Is a tune required to run E85?

Kind of tired of the markup on 93 around here (60 cents more than 87), E85 an entire dollar cheaper. I don't track and it's a DD, can I just straight up switch to E85 or do I need the Lund tune?

You need a tune 100%. Just buy one, wakes up the car. 91 around here is expensive, E85 is cheaper then everything else. You will use about 30% more fuel FYI

Nah, going to skip the tune for a while until the car has more miles. Just bought it and I'm only at 2k miles. There is a ticking sound from the motor but I took it in and they let me listen to two other GTs with the same sound. I don't believe them that it's normal so I'm waiting to see how it plays out.

It's very hard to wait considering I have a SCT tuner from my 2013... :(

You don't specifically need a Lund tune.

You will need to be tuned to run e85. Lund Racing Tune and don't look back!

Lund's. Been good to me also.

Are you sure the ticking isn't just the injectors? E85 will murder your MPGs by 30% anyway. If 93 is 2.85 and E85 is 1.99, it's a wash per unit volume. Not to mention the several hundred dollars you HAVE to spend on the flexfuel tune.
