If so, instead of wondering whether your original engine would still be alive had you not done rod bearings, perhaps the question is whether your rod bearing replaced engine would have survived had you not run an E85 tune in it
I was not e85 running at the time of failure, but yes I do wonder if that caused it. I intend to never tune again but who knows, however, I am not running e85 ever again. The way I drive, I never actually got to the limits of the tune let alone stock hp so it was really no reason for me to even waste money on a tune. Very expensive lesson learned.
