Hey guys, I just got my Stillen CAI today, and went ahead and installed it. After I finished, I tested the car, it ran smoothly, no issues.
When I got home, I ran Torque to check for codes,
and got P0101 and P010B.
Then I popped the hood, and noticed a weird hissing, which I'm unsure if it's normal or not. I made a video of it, you can hear it clearly:
What do you think?
