I changed the engine and added a turbo to my 2005 Mustang GT. It was running so well then it blew the head gaskets! Long story short, put it back together and it made 535 RWTQ and 500 RWHP on a Mustang dyno, then it decided to give me a P012 code. I don't know whats wrong. With that kind of power being made I highly doubt that the timing chains were installed wrong. Does anyone have any Ideas? I really am at a loss, and would love some advice. The only other possibility is the VCT solenoids. Unless the guy that fixed the heads screwed up the cam Phaser assembly on bank 1.
