it appears that there is a little oil residue in the intake ic tubes that go to the throttle body. barely, just enough to feel it. its not visable. I did however have older turbos before the swap that had a bit of a leak. i guess i could check the ic's to see if they have oil in them. I figured that was probably the problem as when i dont go to a + of boost it doesnt really happen. i had divorced dp's and test pipes and hear that they could cause this problem due to little back pressure. IS THIS TRUE?
