The Sniper can be laptop tuned even for those "unfriendly" cams. Holley doesn't push the laptop capability because it's supposed to be totally self tuning, but if you don't have enough vacuum or there are other issues, I can connect a laptop remotely and tune it like it was an HP. When the Sniper was announced I thought I might never tune one, but now I remotely tune several every week. The laptop tuning capability is one of the strengths of the Sniper.
