What is Bosch spec's for CR injectors? Buddies truck is showing...

#1 4.0
#2 0.9
#3 -4.0
#4 0.5
#5 0.7
#6 -2.1

For the Duramax spec is +4 or -4 is it the same for the Cummins CR? Also the numbers don't move around much like my Duramax is this just due to the speed of the ECM?

Nick,

Are those numbers with a cold or warm engine??

With mine I see 2-2.5 as my highest when it's a cold motor. As it comes up to operating temp they balance out to -.6 to 1.0.

The engine is cold, but there is some unburnt fuel coming out of the exhaust so I am not sure exactly whats going on... Commanded and Actual rail pressure is right on so im thinking CP3 and Regulator should be fine.
 
Leaky pintles can do that...high milage injectors???

Might try to swap injectors into diff cylinders and see if the balance rates follow the injector or stay with the cylinder. That can tell you alot.
