I have tuned with this fuel , I have seen the customer return with in 2 weeks and retest and have as much as -5 deg knock on his knock sensor because the e85 he bought the first time was a better quality then what he now had in the car , I have seen pistons burned with holes because of spark knock and know the timing was to the safe side
This isnt myth I have seen it and I feel I am a above avg tuner and tested with my own dynojet to test on , I am not here as some guy that has been told or my friends are doing it , I did it , I saw it , I have tested it
Sounds like below average tuning skills using it in the wrong applications to me.
What cars and what mods?
If you are talking n/a and/or older cars with rubber lines, etc., then I see why you are having trouble.
I've seen people blown their motors on every type of fuel. That's the life when you are modding your car.
