If you asked for an afr readout, then I apologize for not providing that.
I’ve been working on cars long enough to know how to remove a crank pulley, its not an uncommon thing to struggle when removing the bolt. We talked about locking the flywheel but the bolt was on so tight I would have likely damaged the teeth attempting that. Unless we had a tool that would bolt in place and was super sturdy with a good amount of tooth contact to spread the load. Being a former nissan tech, I found it bizzare that you handed me the phone to talk to my old coworker Joel. He said that he had a tool, but no clue if it would work on that motor. We agreed that I would get the tool and you would come back for a second attempt. I had already used all of my last resort ideas none of which damaged anything on your car.
Other than the crank pulley ordeal I thought that everything went pretty smooth. Basic exhaust install and a few dyno pulls. Like I said before, you seemed cool with everything at the time and nobody got the impression that you were upset or dissatisfied. If you had spoken up and expressed some concern about your visit we would be happy to try and work with you to ensure satisfaction.
