There is no best its just whats best for your car and often pocket idealy a custom made is the best for the mods you have but people ofter refere to group N ECU's as the ECU's you could buy and plugged straight into cups and 172's which had maps on them which were created for cars with exhaust and induction kits to take account of the extra air but they were just a set of maps created for one car with an exuats and induction kit not idealy for ever car but they were cheap. Other companies jump on the band wagon etc and call there product group n making it sound racy its just though a set of ECU maps for a car usualy with inudtion and exhaust which they once found were best for one car not th best for all cars with different ECU's and induction kits.
