no the stock ecu will push as much fuel as possible untill it cant push that much. then thats where upgrades such as big injectors, fuel regulator, and pump come into play. however this requires tuning. a fcd DOES modify the signal the ecu recieves, thus running the engine lean...

as stated before: fcd --> ftl
