Holley Sniper first start No o2 sensor

Did a test startup on my new sniper by running the power wire to battery + and not using the o2 sensor. I also capped off the regulated return line with a hose, clamps, and chamfering bit. In the settings I chose closed loop disabled (set to open loop) and also set learn mode to disabled. After a few tries by jumping the starter solenoid I then realized the ignition key was in the off position. Oops, after that it cranked right up. Idle was set to 950rpm so after the vid was cut off I lowered it to 820rpm and it was purring like a kitten. EFI for dummies.
