I talked to a guy and the only thing he said and wont 100% positive on this was "the AD injector tips may have 7 holes instead of 5" which is what he thinks the AA injectors have
He said he had never been asked the question and said "I should know that"
Hope that helps but maybe he'll get back with me and let me know something for sure soon

I belive the ad codes are 140 cc split shot. They do require more oil than a single 160 cc shot stage 1 injector

Thats correct toad, the actual nozzel is not different on the stock OBS and SD 7.3 injectors. The internals are different tho and the stock OBS injectors are 90cc and stage 1s are suppose to flow 160cc and the stock SD injectors are suppose to flow 140cc.
