Its filling a niche of FI for driveway mechanics on a budget and sounds like it works pretty well, certainly better than some of the $2K+ big name systems. Its still cheaper to install factory multi port system. Factory might be a bit more if you figure in flash/tuner to make up for non computer friendly cam but a better system.
I would be skeptical of the electronics of the system sitting on top of hot manifold but time will answer that question.
Lots of these systems have come and gone in last 20 years, holley pro-jection(sucked!!) and lets not forget Edelbrock Proflow injection, worked pretty well if you are a retired nasa computer programming engineer. Accel was problematic. GM TB crap was just that, GM crap. Worked but not for any real performance.
I still think the factory Magnum multi port is one of the best systems going and with tuning, well capable of big HP numbers, cheaper than anything,replacment parts at 7-11 and great MPG if built right. Easily obtainable for $200, throw in a harness for $700 and they both need a fuel pump so I think the cost is very similar.
Keep us informed of long term testing guys. I would be interested in any MPG figures you might have just for morbid curiosity
