The cat-back will be here Friday I can't wait to see if it helps...

Also, again assuming this is my car, the plotted pulls above are with the foglight cover removed if I remember correctly, which is important based on the little testing that I did of the AEM CAI.

Yes, I'll correct it for the two downpipe. Indeed the AEM intake was pretty warm... or more to the point the sensor reads pretty warm. The actual air temp was not that hot, but the sensor heat soaks.

I looked at the logs before and after the foglight, and there was very little difference. A few hp, but nothing huge. Run to run variance was a bit more due to temp changes.
