You all are probobly think Im a moron for asking this but why do the car companies program the ECU's like they do? If the engine is capable of more power, why dont they give it that power from the factory? Are the stock ECUs better for the longevity of the car, do you guys have any aftermatket ECUs in your cars that have been in 100k plus miles. The reason I ask is, Iwant the car as fast as possible but I also want to have it around a long time. Are there any problems that come with getting a upgraded ECU or are there only benefits.
