I don't know if it was a local shop to him, but
@nicholase had some 24# injectors cleaned and flow tested by some company. Might need to ship them. He can chime in on who it was, i can't remember. They provided flow charts and all that which was more than i can say for the local shop i had clean/repair and flow test my 19# injectors. They did the job, but was kinda rinky dink if you ask me.
