As Lilpooh points out above, you need to know what you are doing. It is no longer Sniper. They are Delta Force now. They have a pretty decent product but not too many tuners support it so if you go that route your options for tunes will be almost zilch. Unless you do know what you're doing or have someone to work with you that does I would stick with SCT.
You can also get the pro racer package from SCT and write your own SCT tunes.
