I've been looking at them too for several months now. I have down loaded and read the instruction manual. Besides the unit's adaptive learning capabilities the laptop set-up and tuning software has me sold. I'm going to buy one I think if they will crank out the 1200 cfm version. Much mo better than any carb set-up and much less clutter than SFI. Although SFI is superior as far as fuel injection goes.
