SE take two! Err, make that three!

So if I'm reading this right and I'd like to think I am this is your 3rd motor and the first 2 blew from corn and your 3rd your switching to 93.
I'm kind've scared, I'm currently undergoing a massive build to from a 2.0 16g corn fed to a 2.3 stroker with a FP black and with the numbers I want I'm sticking with corn. I guess my question is do you know what went wrong, is corn that unpredictable, or was is it all in your the tune?
