So you were tuned for the 3.85 pulley... went down a pulley size without retuning it and car went boom. I would agree it was too lean and detonated. Piston before you cleaned it looks like it had a pretty good hotspot in the middle there where it's black

For fueling DI only on E85 you will need... +30 injectors, LPE DI pump, and a low side upgrade(LT4 with JMS minimum, Cordes Aux better, Fore Triple pump best). The Cordes setup should work well.
On a 50 degree day I am hitting a peak of 12psi(10 psi average) and I am injector limited to E45 with LT4 injectors. When it gets above 60 degrees out I can run E60. Fuel system-> LT4 injectors, LPE DI pump, LT4 tank with JMS. High side drops a little up top 2900 to 2600psi, Low side holds 70 psi, injectors right on the edge at 5.9-6.1 with a .81-.82 lambda target. My next move will probably be +30 injectors, lower commanded rail pressure to 2400 psi, and that should allow me to move the E content back up to E60 in the winter and full pump E in the summer. This setup uses more volume and less pressure which gives the system a little more time to recover and keep fuel in the lines. At least this is what I experienced when tuning my brothers C7Z. It's heads/cam 2650 with 80mm pulley, FIC +30, LPE DI pump, cordes low side. Should be over 900whp on E.

Is anyone running the 15w50 mobil 1 on the stock bottom end on the ss. I just dont like the look of things with the 0w40 mobil 1 and the shear is low for gas mileage. The cam berrings dont look great either so Im wondering?
