Cleaned the turbo, now shifting hard
I pulled the turbo out today to clean it up, since I'm pretty sure the previous owners haven't touched it. 154k miles...
Vanes had some pitting, not too bad though. Some wear on the unison ring, also not too bad. Cleaned it up real good, made sure everything moved smoothly as it should before reinstalling it.
Did KOEO x 3 before starting it back up for the first time after reassembly. Went for a test drive afterwards and it is shifting hard at WOT. Boost pressure is fine, as is acceleration.
What could be causing this?
