Tiny metal shavings in soot on throttle plate...a warning sign?

[Rice Over Wheat]

I'm installing my coolingmist kit and so I took off my TB elbow to tap for my dual nozzles. There was a bit of a layer of grime on my throttle plate, so I wiped it off with my thumb and noticed very very tiny metal shavings in the soot. I'm thinking it may be from the FMIC I installed several months ago. This is before I started tapping holes in my TB elbow out of the car. Any ideas what this could be and if it's a warning sign of anything, such as a turbo going bad or something? Turbo still pulls great and last I looked at the fins there were fine and no play. If it's just particles from the FMIC they look small enough to be incinerated in the engine. Still, I want to be sure it isn't something serious.

Could be from that, could be the throttle plate rubbing up against the throttle body. I've never heard of shavings coming from a turbo, but I suppose if the compressor blades were hitting the housing, then it could be possible. You'd probably hear your turbo making some noise though.

Well I remember seeing lots of dust in the ic piping but didn't flush any of the pieces before install. I just wiped them off best as I could and put them on. Thanks for the input, hopefully you're right. I'm thinking that may have come from where the welds were sanded down.
