Anyone have any solid experience with this on an 07 STI?
How many people are currently running their 07 STI's without this pump, entirely removed, and have they had any issues?
Plug in the air pump system valve that has the bigger sensor on it. It contains the Atmospheric Pressure Sensor. Disable the codes. It will run kinda weird on cold starts, but you can adjust the cold start enrichment fueling tables for it. I have no air pump. 2 catch cans take up that spot instead.
