i know this gets asked more than anything but here's my situation.
checked with predator
in park- in drive hot
#1 -.94-#1-.46
#2 -.35-#2 -.57
#3 +.15-#3 -.23
#4 -.88-#4 -1.01
#5 +1.04-#5 +1.46
#6 -.12-#6 -.88
#7 +.53-#7 +.96
#8 -6.03-#8 -5.33

commanded rail pressure 34 mpa
actual 31-38 mpa

idle fluctuates between 650-690 rpm

once and a while i get a bit of smoke at idle, bits a blue ish white. that could have something to do with the bit of 2 stroke oil i run. no fuel in crank case and no loss of power but its about time to change #8. what do you boys think? and where's a good place to get 1 good injector lol

Two stroke oil has never made mine smoke. I'd say #8 is your problem.

I had balance rates very similar to you. I let things go until limp mode and fuel in the oil. Decided to roll the dice and replace my #8 as the rest looked great like yours. Did NOT fix it. Replaced the rest and fixed. I wouldn't rely just on the balance rates for isolating a bad injector. I got my injectors from Pensacola Diesel.

yeah might have to take it to the stealer to get the return rates checked.
