Top speed increase on Penner Tune?

[Here4now]

What is the most someone increased their top speed to safely using the Penner Tune?
Thinking about increasing the top speed on a stock 2022 GT. Looks like you have to select the top speed to enter instead of just removing the top speed in TuneECU.

Pick the highest number you can. Power and drag will set the limit for you. The 2021 R3 GT we modded and took to Bonneville in 2024 and 2025 could hit 186 on the dyno. We got it up to 173 on tarmac. At Bonneville our record run in 2024 was 148 and in 2025 was 154. Riding on salt is like riding on ice/snow. A tad-bit slippery.
