Anything said would be pure speculation. You need to data log and put the car on the road and drive it to uncover its issues if there's no DTC's yet.

My gut theory would be contaminated fuel. Since you run E85, that stuff thirsts for water. Fuel additive does help, but separation can occur in fuel that sits. The higher the E content the more risky it is to let it sit. DI fuel systems put up with water contamination very poorly. Though your symptoms still fit a multitude of other possibilities. Checking your plug wires would be an easy place to start. Purging your fuel system will be a bit of a chore.

Do you notice any smoke from the exhaust pipes? If so, what color?

As far as free reving, I don't drive until the oil hits 100. I don't rev beyond 2500 until the oil hits 190. I try to give it at least a good 10 minutes at operating temp before I do any real high reving. For me it's not really an option, as the Procharger needs time to get its oil up to operating temp as well. Between the engine and ridiculously expensive head unit, I'd rather not have any failures or damage be due to lack of patience. All that BS aside, I don't think what you did caused any damage for what you're describing unless you had an oiling problem to begin with, and even then, if it had been related to oiling and a part failed, you'd hear it in the engine. If you are hearing odd engine noise, it could be a collapsed lifter or bent pushrod or rocker. If you do, you could dump the oil to check for any metal/debris and capture the oil in something transparent to observe for separation. You could do the same for your fuel, disconnect the primary feed to the rail and have someone prime the pump a few times and capture the fuel in a transparent container to observe separation. Without more data or additional symptoms, the speculation just gets wild from here.
