A modified car will never be reliable, Having the AEM played a big part in getting my car where it is. Piggybacks can make power, they just dont work as well. Also the driveability of the AEM shits all over the stock computer. When i put in the AEM it was like going from a Taurus to a Cadillac. Everything is just smoother, and works better, but i have a great tuner in my corner.
