I always run 11.0-11.5 to be relativly safe. I don't think I would ever set the car up to run past 12.0 on the bottle.

I also shoot for a flat 11.0 It also depends on how much your spraying IMHO
if your only blowing a 100 shot then you would be OK with a 12.0 I would definately stay at or below 12.0

We tune most of our Nitrous cars around 11.8 to 12.1.In some casses we will go as high as 12.5.Depending on the customer.

So whats the real danger in the higher AF numbers besides obviously leaning out!!?? Is it more for insurance if the pump or injector or something fuel related fails!!??
