I had mine done last year at a CEG meet. Jerry from Superchips did it at Dyno Dave's. Since the computer is flashed, I know it doesn't lose everything if the battery is disconnected or if fuses are pulled. But because it doesn't lose everything, if mods are done, does the computer recognize them or does it have to be reflashed to make a difference? I'm changing from a KKM filter to a K&N filter and I'm wondering if it's really gonna matter. I've also had MSDS headers installed and really didn't see any difference at the SZ05 dyno so I'm really wondering what my next step should be.
