Well I have an air sucking noise that I swear was coming from back there.
Gunna check it out again tomorrow but I can’t imagine what it would be unless the intake side of the egr valve is cracked, but that’s closer to the top. This definitely sounds like something behind down by the exhaust.
I wiggled around the line going to the map and the brake booster but the sound didn’t change.
LTFT on my aeroforce was -14, but it always ran in the negatives... I think the Overkill tune is just rich... if I had a vac leak loud enough to hear like that, wouldn’t I have positive ltft’s?
