yea the engine management forum at HMT kicks ass, but search first cause they hate noobs that post what they think. But basically, when people say their ecu's are chipped, they're really socketed, which means they're capapble of installing and removing a burned chip. The best way to tune your car is have someone hook up a wideband O2 sensor to it, and then load up a basemap on your ecu and see how it runs. Then if the person has a romulator, they plug this data cable into the ecu which temporairly loads a program so you don't have to burn a chip, and then you do another pass to see if the changes have improved anything, and keep repeating the process. Once you're tuned, you burn you final tune onto a chip, plug it in, and done.
