A buddy of mine let me install a set of 215's that were hogged out to a larger injector since I was under the impression that my injectors were stock but once I got his in I seen a drop in performance.

I have these codes on the injector.

0325 - at the top near the fitting for the injector line
KDAL59P6 670 on the body

Bob's hogged out 215's have code
6818 up top
KDAL59P6 566 on the body

I'll answer my one question (this is after calling around and speaking with Cummins service dept and a local diesel performance shop) so that if anyone else has this question they will have the answer...

Both are 215 stock injectors not since Bob's hogged out ones actually cause me to loose power then the ones that came with my truck had to have been honed out as well but they were done further. After speaking with the performance shop they believe that is the case because I have what I call a shake or miss at idle with a slight bit of haze out the exhaust - they said this is typical with higher end injectors in the mechanical 12v's because not all the fuel is actually being burnt correctly/fully.
