Larger primary turbo for SPS62.

My setup has been fine with the SPS62 and the K31. But I am not sure if the primary is putting out enough air. I am not having any major egt issues, but I do have alot of smoke at full throttle. I have been thinking about going to the larger version S400 as it is not a difficult swap. I hit about 32psi off the bottom turbo and about 62-65 total. The wastegate on the primary is set to start opening at 30psi. I wonder if an S400 might help clear things up a bit.
