I would have a hard time spending close to $100 on a 0 psi setting switch.

Save the money for a chip etc. (performance upgrades)

 

isnt that the definition of lean- stoichiometrically more air then fuel? so if there is zero fuel and all air, then it would be full lean, no?

also a friend of mine drove his car off a 35 foot cliff because he didnt think about what would happen before he decided to turn the ignition off to save gas while going down a winding hill. he forgot about the power steering and brakes part of it. im surprised he didnt break anything besides the car. its probably worth the extra 3 cents in gas to keep your breaks functional.

 

Lean means there is more air then fuel, but once you remove the fuel from the ratio it just becomes air so its not possible to be lean if there is no fuel. At that point its called "Free Air". Most wide bands will show a % when doing this instead of showing a AFR.

 

$100 to install an on/off valve between my n75 and Wastegate? I think not... But I have nothing to reference so... lol
