The actual cruise speed performance table from Tornado Alley Turbo for their SR22 STC (the same one for the currently sold as-new SR22T). I’m stunned my mod tweaks got me amazingly close to that red curve line. In fact the performance of my tweaks pushes that curve more steeply up after passing FL200. I’m still trying figure out where it’s generating the excess power. But not a bad outcome for a couple of hours experimentation on a rainy Sunday…
