Airdog & rail pressure

Those of you with Airdog II setups, did you notice a significant difference in rail pressure after install? I am really debating about getting my old man an Airdog II for his 6.4, just wondering how bad its needed.

Anyone have rail pressure info before and after Airdog II? Preferably with 200+ tunes.

These trucks dont really need an aftermarket lift pump until you start getting into injectors. A healthy stock lift pump will support 300+ hp tunes all day long. If you install one I doubt you would notice any increase in rail pressure.

What he said ^^

Im going to get the AirdogII soon, mostly just for peace of mind. Hearing about all the stories of water in fuel messing up the whole fuel system and lack of PM makes me worried.
