Stop in for a cup of coffee
That's one area I'm a bit unsure of.
On the holley forum they have numerous complains against the sniper kit, other than it being non serviceable unless sent it for repairs it has repeated ecu failures.
But those failures are split in half between legit cases of a failed ecu and improper installation. Which is why they hammer hard on wiring & proper power & grounding in both the forum and instructions included with the kit.
