I think that either Superchips or SCT Xcalibrator are the ways to go. How much you get out of it depends on the tune that is put on there. Stay with someone who tunes a lot of Lightnings, and you'll prolly stay safe and get the most out of it. I had taken the chip out of mine and went with SCT Xcalibrator by a well known tuner near me in NJ because I eventually had contact problems with the chip installed, especially when it got cold out.
