Zero shift play, no nicks. No signs of seals leaking. I was using Stratified and was happy with what i got from them, although any reputable tuner found on these forums would do you right. My performance goals were to just bring the turbo up to what it could safely deliver for power on 93 and E30 without overspinning it. The marks you can see in the photo are clean spots (there's an extremely fine layer of oily residue on the impeller) from me testing how smoothly it still spins with a plastic pen.
