You will be fine with a stock fuel pump...Of course an aftermarket would be better but the stocker will get it done, I run smarty tnt which is very aggressive and i still have like 3-4 psi left of fp.

dyno results: 113 degrees out side, crazy larry:431hp 858lb performance setting 376hp 699lb performance sounded good but crazy larry i thought would have been much higher

the other thing i noticed was the truck started out with a blackish gray smoke then worked its way to a whiteish smoke while dynoing. when i origanaly put that program in about2-2.5 years ago it would blow nothing but jet black smoke never gray. i havent run that program in my truck for well over a year sense reading up on how people burnt injecters with it because of the stock pump. the truck also doesnt seem to have the power i remebered it having, it seems like it could be lacking abit. the truck starts up fine no smoke doesnt run rough just doesnt really blow the black smoke like it used to. i noticed this a while ago probubly be fore winter and never thought anything of it until today when i was like what happened to the smoke it used to blow. any ideas or is it just me?

When I started reading this thread I was going to tell you what I got with CL and a boost fooler, that's 443 so I knew you'd be in that range.
Get a fuel pressure gauage though, I was able to draw it down to zero PSI running extreme and CL. Didn't like that so installed an AirDog.
