So far my impression of the 91 perf/street is it is very crisp. Awesome throttle response and smooth shifting. Haven't went WOT yet but I am sure I will be happy. I was afraid I would regret not going with the 5* tune I had on my '11. Best part of it was throttle response and low end power. This matches it if not better.
