I had a 10th Gen Si and ran both tunes. I found the Phearable tune to definitely be more tuned to bottom end and was a little more aggressive with the turbo spool compared to TSP. Honestly though I ended up going back to the TSP tune just for the better/smoother driveability.
That said, I have NO IDEA what kind of changes they may have made for the 11th Gen but would absolutely love for someone who has experienced both in an 11th gen to chime in!
