[QUOTE="MysticRob, post: 12979039, member: 118642"] Your questions are a bit confusing so not sure exactly what you're asking. The factory tune is rather conservative, and can't account for large mods like pulley changes, etc, and the vehicle will not run correctly and might lead to engine failure (ie lean condition). Therefore the tuner will custom tune the car for the mods, first loading the factory tune in the handheld, then loading that custom tune into handheld (there's room for multiple tunes in the handheld), then loading the custom tune into the ECM. If the car is returned to stock, simply use the handheld to reload the factory tune that's still stored in the handheld. The factory tune might be able to be stored in another medium besides the handheld but I've never heard of it being done, and not sure why anyone would want it done unless they're concerned the handheld might crap out. :beer: [/QUOTE]
