Bad news on the update. Cleaning the direct and port injectors did not fix the issue. Misfire on cylinder 2 on cold start but when start up sequence finishes, does not misfire. I haven't driven the car yet since it's at the shop but they said it drives fine once the start up sequence ends. Redline pulls in 3rd gear no misfire so they think it's the tune or maybe a sensor is bad.

Swapped coil packs around, new spark plug in cylinder 2, fuel pressure good, compression and leak down good, no carbon buildup on valves.

Kinda wished I didn't fill with e85 to see if it cleared things before sending to shop. Need to drain or use up the fuel before switching to stock tune to see if its the tune.
