Make your gas engine behave like a diesel?

The members of this board have previously expressed doubts about this concept (justifiably so), BUT some of the information on their own site would suggest that negative supercharging only works in the middle rpm range, providing a big boost in torque at that range but totally choking off the top end rpm power of the engine. So even if this all worked 100% as described, this would mean you'd have a massive torque peak at 2500-3000 rpm, and less power at 5-6000 rpm than normal. So you'd have to drive it like it was a diesel engine, keeping it in the torque peak as much as you could (and sometimes you would not be able to due to gearing limitations). The linear output of the conventional gasoline engine appeals to most people over the limited-range output of diesel engines.
