The CEL came on yesterday and using Torque I saw that the code is P00BD. Basically airflow is too high. I bought some MAF cleaner and sprayed the entire unit and then sent the clear command via Torque. Still have the CEL. How can I clear it and will it cut power until the CEL is cleared? I don't seem to notice too much of a drop off, but what do I know. :/

Did you shut the engine off with accessories in on? That was my issue I was trying to clear code with the car still running.

Turn your car off completely, then hit the start button once without your foot on the brake. Accessories should come on, then run the clear.

I had the same code and the only way I got rid of it was by swapping back to stock. Then installing the tune later.

Try disconnecting the battery for 30-60mins.

Reconnect battery

Thanks for the reply guys. It looks like my car just needed a night to sleep on it. I hopped in this morning and when I fired it up for its morning cold start the code was gone. I've heard of others running this intake and either being able to clear it and never see it again or having to constantly clear it. I hope I'm in the former group.

Bent did you notice any jerkiness when originally installing the intake? I installed an Injen Intake, ran fine in the morning, installed an AA8 tune, and got a cel. I am hearing two "woosh" noises as well from the left and behind me, made me think maybe the Charge Pipe blew but not sure on that one.

Only jerkiness I notice is when I get the rpms too low like being lazy and not downshifting from third to second. Other than that; and the CEL of course; everything has been fine.
