New 4150 style Sniper EFI

For what it's worth, I installed the MSD Atomic on my 440. It works perfect. It doesn't get a lot of press since Holly bought MSD.

I've installed those before. They seem to work okay but the features are really limited. I doubt the Atomic will be around much longer since the Sniper is roughly the same cost but has a ton more capability. Holley is probably just trying to figure out how to gracefully shut down the Atomic.
