Can an Engine run on an engine test stand with a Holly sniper FI unit?

Break-in has to be a smooth, no problem, start, time, monitoring guages, ex temps etc. to ensure success .
My kids had to mess with this and that trying to get the injection working, fuel ratio, fuel pressure, oops, a leak, train to idle, yada.
I believe it would be in both of your best interests to KISS .
Keep It Simple Stupid .
If you are really familiar with injection, - absolutely sure the cam break-in won't suffer? ?
When you accidently drop a slice of bread and jam?. - does it usually land the way you want ?
I wouldn't gamble .
