Holley Sniper EFI

So the problem I had is repeating itself again, only this time I got the car started. The engine goes to start and then as the key is backed off the engine tries to catch to run and coughs up white smoke. After the 3rd time I tried it, it caught and started running and idling. The IAC when it starts is at 100% which makes a loud sucking air sound and it settles down to 40% as the engine temp warms up, air noise goes away as well.
Try adjusting the butterflies to be a bit more open, and then reset the unit so tps gets zero'd out. Also check rotor phasing was the correct way. What's your initial timing at?
