Took it out for a nice drive today, finally. Seems to be running much better, no misfires on Sport map. Since I was getting them even on the stock map, just getting on the expressway, I'd say this solved the problem. I did a lot of pulls, including one from 30-75 onto the expressway, and it never threw a code. Still seems to be adjusting after switching maps, but it seemed to be pretty much dialed in at the end of the drive.
My oil temp stayed between 228-232 the whole drive, water was around 200-202. And maybe it's a placebo, but I popped the hood at home and overall the engine seemed much cooler. Wouldn't be too surprised since it's probably running more efficiently.
