Default Nozzle size/progressive controller

This is my first post, I posted this on the Turbo dodge site but haven't had any responses.
In a couple of weeks I'm going to be ordering the Devil's Own progressive injection setup. I am curious if nozzle size is as important with the progressive system as it is with the base system. Basically, does a large nozzle have atomization problems at low pump pressures? I would like to use this kit to improve my fuel mileage by advancing the timing and possibly pulling my fuel pressure back. I also plan on eventually raising my boost to 30psi. I know more fuel will be needed when raising the boost that high, but will a nozzle designed for boost that high also be effective with everyday driving with the water coming on at 5psi?
Thanks, Steve

Low pump pressure is never a issue, the controller will only allow a drop so far in pressure, Our system with open hose is 40psi (no nozzle in place) That is the nozzles minimum atomization point. You will gernerally never see below 80psi of pressure.

Gas milelage is subjective it depends on how you drive, most people tend to get more aggressive after they get the kit (it's additive). Depending on your mods and how much boost is what determines what nozzle size you want to run. With the progressive kit it's very effective at low boost levels you just have to adjust your setting to your liking.

Is it still better to buy your kit from FWD Performance or directly from you guys?
