I have no idea what pressure should be but I am curious about how your installation goes. As I just mentioned in another post, I just tried to hook mine up and it is cuasing some problems.

As it happens,..
I bought two new cp3s (oem) and tested both prior to putting on my dual cp3 setup as I wanted to be darn sure they equal or as close as possible to one another for balance in the dual setup. They tested individually as follows:
Cp3 #1 = 21.7k
CP3 #2 = 21.5k
They both would fluctuate a little bit on shifts etc but those numbers are at wot. In tandem now on the dual setup they are right at 25k psi and are rock solid.

my rail pressure stays at about 22k with a stage 2 pump with a smarty. when I turn the tst up the truck gets down to 15k or so and it cuts out then. dual pumps are on the list. then im going to buy huge injectors if I ever get them
