I have a 2017 with the OFT e85 tune, high flow air filter, catless front pipe. Been running the tune for about 1000 miles with no issues.

There's a super long freeway on-ramp that I like to use to have a bit of fun and typically go full WOT through 1st, 2nd, and 3rd gear, before slowing down and entering the freeway.

This most recent time, as I was in 3rd, the car lurched as if I had redlined. I looked and saw I was only at 6k RPM. So I shifted to 4th and gave it only about 50% throttle. Car lurched and lost power at 4k. So I just shifted to 6th and tried to go freeway cruising speed, but the car kept lurching and losing power and struggling to maintain speed. Eventually all the dash lights came on for a couple seconds and the car made the beeping noise as if I had the door open. I pulled over, keeping the car on.

I kept car idling for about a minute, all the dash lights were back to off. I revved it a few times and nothing seemed wrong about the revs, I found a spot to merge back into the freeway with about a 75% throttle first and second gear pull and there were no more symptoms. The car acted normal the rest of my drive.

Is it the tune? Did it go limp for some reason? Or did I fuck something up?
