Agree. Holley Sniper/Terminator user here. Data logging is a really helpful tool as is the ability to build your own tune. If you’re willing to use a laptop to make adjustments after the initial set up the Holley software is very good.
Sniper has limited features and I don’t believe it’s even available for a MP application. It’s really more of an entry-level system for replacing a carb anyway. The Sniper ECU is in the throttle body.
For MP you should probably look at the Terminator or Terminator X. It’s more advanced than the Sniper as far as options and having the ability to add things. Plus, the ECU is separate from the TB which is a good thing. The Doninator is even more advanced and can do all sorts of things if that’s your goal..
