how do you guys adjust for weather? Put the info in the Davenport software and change the main jet, change the pump loop, or do it with a timer? Do you also change the barrel valve so you have the same fuel flow every time at stage or do you "let it ride" and it is what it is with the main jet change? What happens if the weather gets real good and the Davenport says put in a blank? Will the car start idle and stage like normal?
