Hello everyone, I've been a stalker and poster in the forums for awhile, I have had my Stinger for about a year and a half now. I recently de-tuned my car as I had to get my Cyl 5 Boot replaced (it was acting funky for some reason) and it runs fine now that it's been replaced. It has been about two months since she was last tuned, so I activated the JB4 and started with Map 2. All felt fine, so I jumped to Map 4 and 5, which for the most part felt fine, but there were some strange blips that I'm not sure about.

I'm no expert, but I checked the logs and everything seems fine? I know that in one of the logs Cyl5 (ugh) pulls 3 degrees the whole way up, but that isn't even the log with the issue. The issue is the OTHER log shows a throttle cut (with pedal fully down) and I can't figure out why. I was going pretty quick down the highway so it's not like it was a loss of traction or something. It does continue to replicate the issue if I keep flooring it. Not just a one-off.

- Also, to note, I have intakes and Denso Step 1 plugs. Don't ask me how long it's been since I changed the plugs.. but I checked them maybe 3k miles ago and they honestly looked great. Shiny probe and all.
- I'm also running probably about E20, but I did the math, it could be anywhere from 15% to 28% depending on corn % at pump. Manual fuel bias set to 118.

TL;DR: Re-tuned car after a couple months, replaced Cyl 5 Boot, throttle cuts under high rpm w full pedal, checked logs w/ no major issues, aware of Cyl5 degree pull.
