Total seal rings and turbos dont go well together, I really prefer a file fit ring in that type of application, especially with forged pistons. That being said total seals makes a NICE file fit ring, they have a really high quality control so you end up with a nice product.
If the top ring is chromoly, which I assume it is, then the best (only) way to get them to seat correctly is with cylinder pressure. With a turbo car I normally put a small spring in the wastegate and use part throttle pulls to seat the rings, like 2,000-5,000 rpm, in second gear then engine brake down. You want to be sure to vary RPM, dont go on a long highway drive, for the first couple hundered miles. After that change the oil and put the boost back up to where it should be and you'll be good to go assuming its tuned correctly.
