Hello all,
I did some searching and found little info on what all influences the Injector balance rates. I have an 06 3500 with a fresh rebuild. Cylinders 1 and 6 were fuel washed and needed to be worked. I had the head and block worked before i reassembled with new internals and all bosch factory rebuilt injectors. I have 3k on the build now and it still seems like something is wrong. Only aftermarket items are a sinister fuel filter, fuel rail return block off plug, ats 3000 turbo, intake and exhaust.

Attached is a short drive logging commanded fuel pressure and desired fuel pressure as long as a period of idling before and after to view injector balance.
From what i see it is increasing fuel to cylinder number 6 to try and balance. It sits right at +4mm which by what i have found on here shows to be a dead injector. However it was replaced at the same time as the others, what other factors could I have in play? I re torqued the connecting tubes with no change. The only options i can think of at the moment is maybe that valve lash is set tight on that cylinder causing it to have lower compression, or maybe the injector really is just bad.
Any outside imput is welcom....
The truck used to have a smarty jr on it, so im locked from doing much with it until i have the computer re flashed to factory
