I've actually searched for exactly that for a while, and never got a clear answer, so the answer must be no. I think the sniper can only display a kPa and a psi reading(in the boost parameter). You have to use "math channels" in the display or something like that to enable it to do its thing. If it could possibly be changed to inches/mercury, I've never seen anyone write up how to do this. Sniper does allow for some inputs into one of the weather pack connectors. Its nothing like what the Holey HP or Dominator can do, this is a base holley setup, so it wasn't designed for lots of add-on's.
