To tune or Not to tune?

Yeah, I really doubt the turbo is bad as well. The seal I was talking about is internal to the turbo, and should be new with the rebuild. I don't know if its normal or not, but when I got my new-to-me 57 trim from Driftmotion, mine did leak a little oil into the compressor side (I poured oil in the CHRA to lube bearings and such before install). My understanding is this is normal, and turbos normally do seep a little oil into the cold side.

I had to tighten the $hit out of my silicone couplers, way tighter than I thought they should be, in order to stop the leaks I had
