After driving the car hard pretty hard and spraying twice 19psi+70shot. I noticed the unported E6 was glowing really bright. The A/F (I know its not a WBO2 but...) was showing one bar in the green. I let it cool down completely. I drove it home easier and it was glowing slightly at the flange and the exhaust side of the turbo. Seems to run fine. What possibilities am I looking at? If it were the cat it would glow at the cat instead, right?
