I'm new to the forums and have been digging through everything. I have not seen much on tuning, I could have over looked that area somehow. If its here point me in the right direction. Reason I have been looking is, the 2023 Durango Hellcat I bought was tuned and I tracked down the shop that did the tune and got the a sheet but it has an odd thing going on. Anyone ever seen this in a dyno sheet? I may have to go back to the tuner and have them look for other sheets and ask what this is and where are the other sheets.
