Yeah, I know that tapping plastic will require no oil, as there is little to no heat that will be produced, at least relatively when compared to tapping aluminum/steel.

The oil would be an effect to group any chips together and hold it in clumps instead of having the smallest chips break off and going everywhere. Then having the shopvac underneath the hole to suck up the clumps that fall.

While the idea of turning the car on seems that it would work, wouldn't there be vacuum from the opposite side of the tube (closest to firewall), and nothing really "pushing" from the turbo side of the tube? I mean granted the turbo would be spinning from the exhaust gasses, I feel the car would near stall from the MAF sensor having way off readings of airflow..?

What I did was to remove the upper hose going to the throttle body and put my shop vac hose in it, make sure you remove the map sensor first. After I was finished I left the hose off and started the car in the hopes that the boost would blow out anything that the shop vac didn't get, then hook up the hose. You may have to clear a few codes from not having the hose on.

I'm worried about getting plastic chips into the tract, but planning on using a bit of oil and a shop vac in the hose underneath to help as much as possible to avoid it. I don't really want to remove the whole bumper to get that whole pipe out.
