So I've run into a very confusing problem. 2 nights ago I filled up about 40/60 E85/ 93 and the car was running great. Drove through about 4 gallons. Parked the car and the next day I fixed my battery cable issue that I had. The cable was frayed and was causing charge issue and was only putting about 12-12.5v to the battery.All went fine with that. I rehooked the battery back up and all of a sudden I have this crazy odd issue. If I floor the car it won't rev past 3k-4k and will start misfiring or atleast sounds like misfiring. I have thrown some random misfire codes across different cylinders.

1. I don't believe I have a vacuum leak because i unplugged a line after the car was off for a while and I heard vacuum. I also can hear a clear difference when unhooking a vacuum line while the car is on

2. It seems almost like traction control limiting and it doesn't throw misfire codes all the time. It just sounds like it sorta.

3. It builds boost and you can hear it clearly.

4. I can rev the car to 5-6k if I gradually increase it and it sounds fine. It's only if I floor it.

Any ideas?
