Last year I had my PCM reflashed in my 2012 GT PP1 by Roush via a local Ford dealer. They don't use the same trans relearn that Ford lists. They say drive it around in normal mode only, no paddle shifting for a tank of gas. I did that and since then I have a 4th to 5th flare from 100 to 500rpm. Only in sport mode or higher and only at operating temps.
Now there is another revision. They won't say why but they say anytime there is one to get it. Anyone have this done on a 2021? If so, did you notice anything? Know what this revision addresses?
