It will be aftermarket ecus that come into play no different then the automotive world. And yes, they have a much broader torque band then a two stroke. I ran a prop on the 300r that my 300X wouldn't allow to get on plane. There is a big difference. 135-140 mph small tunnels will be out there soon "not that this is a good thing" but it will be available.

It was just documented on video (25 liberator with a "center pod" and 400Rs with 1.75s running 125 with crazy acceleration getting there) now take 400 pounds out of the picture and add a 1.60 back into the picture=crazy speeds and accel. These motors are changing performance boating and will be worked and modified for the next decade to come.
