When does vacuum advance kick in?

With the Sniper keep in mind you can also lean out the AFR’s in that cruise range too. If you go to Holleys tech site you can find some examples that will give you an idea of what can be done. I found some and customized the idea to what I was doing.

Oh, I know. There's a Sniper EFI Facebook page also, lot of really good information on there also. Lots of adjustability here. I do not have the cable to hook up a laptop direct to the sniper so have to save to SD card, plug into the laptop to make changes but it's not that big a deal. Still learning (I got a long way to go) just how all this works and how it effects the engine.
