Dyno shows these at 420 to the tires. Have not tried a Boss version because the price difference does not make sense for this install with a custom tune. I like the potential of the new Aluminator 5.0 offerings though. We have a potential customer in MA that may go this route but the clock is ticking on registrations in MA.

You can wind these out to about 7500 or so rpm. Cold roads so I have not gone beyond 5500 today. Working on a drive video now.
