So correct me if im wrong. To spray nitrous dry all i need is to put a dry nozzle anywhere in front of the maf. Don't need to mess with the fuel pressure regulator. I just let the maf add the additional fuel? sounds too easy. thanks for your help.

 

yes its that simple.

 

will the maf read dif amounts of n2o? or will it run rich/lean untill u have the correct amout of n2o?

 

The MAF will add the nessesary amount of fuel for the size of the shot. On a bolt on only car you will be running out of injector at about a 125 shot.
