Keep in mind that this product isn't being represented as the ultimate standalone ECU for high-end/ high-horsepower builds. But for the majority of bolt on 450 to 550+ whp cars it is certainly a fully capable and economically competitive option. When you consider all of the other electronics that you don't have to buy its down right cheap. Now if your looking to build a 700-1000 hp car obviously a higher end ECU would probably be more appropriate, and the additional cost that a system like that runs wouldn't be a major consideration.
