Alright, a couple quick questions-
I was told by a shop/tuner that the sensor everyone is concerned about measures the air that the pump in pushing into the cat, pressure wise.
So that removing the unit and all lines/pumps/solenoids is fine and any check engine lights can be removed without harming the car.
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?
