Great news, I unplugged the rear o2 sensors and egt which were hanging in the air, and the car is throwing no codes and not running into limp mode, even at 8000rpm. Idle isn't perfectly smooth, but the ecu might need time to adapt, or I'll weld in the rear o2s and egt if it does not. Car feels very strong up top, hoping to dyno it this weekend.
So basically there was nothing wrong with the kit, or install. Just some bad luck with the guy who installed my euro headers with the sensors all backwards
I'd like to mount it in the coin tray area, even temporarily, since thats where the permanent install would be, and I'd only be running the wires/hoses once
It looks like this, and you can change the surround to silver and the face to white, but I'm staying with all black
