I see what you are saying about low dilution ratios. Although I'm not sure what Lund would say about that(or what they technically could say :) I dont know what the actual data is (both tune and power) on low level E dilution is, or how beneficial it actually is without a tune. I think the danger here is how "run E85" is defined. You can imagine that this throws it into a big sea of variables. Some people put 3 gallons on top of 13 and some would put 4 gallons on top of 4 gallons of gas. There is just a LARGE window of improper low level dilution possibilities which means if people dont educate themselves, it leaves open the possibility of engine damage.....IF there are truly any appreciable documentable advantage.
I agree 100%. A word to the wise for those doing this without a tune would be: Make sure your ratio is perfected and of course safe and never deviate from it, unless you decide to get a Flex tune, in which case you can mix fuel ratios until your heart is content.

you can run e85 in a mustang without a tune. The computer is able to compensate. However it will throw a code.

I have used E30 with no ill results. Long term fuel trims run around 10 %

Yes you can run it without a tune and pick up a little bit of power too. Have a look here. A Flex tune allows you to run any combination of pump gas and E85.

That's horrible advice. Do not run e85 or any mix of it. You need a tune. Mustangs do not come with flex fuel logic but the f150 that Alex ownes and tuned does have factory flex fuel capability

Lol The horrible advice comes from within.
