They got a P0304 code. They checked compression on cylinder 4 and it was super low. He checked the stillen tune that they sent AR_Auto and it had no knock protection or timing in the tune. So this is Stillens shitty tunes fault. So PSI stopped there and said we can’t tune a hurt motor. So now my brand new 2018 370z Nismo is fukd. It’s now back at AR_Auto and they said they will put a brand new motor in but it’s a month out from Nissan. So this is my update. Sorry if I don’t respond back until I get more info. I can’t believe stillen is willingly sending out tunes with no knock or timing. I just paid $45k for this car.
