Probably a decent system for a cruiser, same with any throttle body system. From what I've studied and seen on the chassis dyno, takes a MPFI unit with lots of tuneability of both the fuel and ignition curve to get any real high performance numbers... but if price and simplicity is your main criteria then it might be ok. From what I've seen of other products by the same manufacturer the quality leaves a bit to be desired, but then it doesn't cost $4K+ like a FAST system or the Edelbrock Pro Flo II system....
