The engines that blew have way weaker rods and pistons than the 14-15's do. It has been proven by Tork and a few other companies that Kia/Hyundai did do a revision on the pistons and rods on the 14 motors. The 15s have the strongest rods and pistons so far but doesn't mean that we won't see LSPI events at all. All GDI motors can have a LSPI event happen. Just the nature of the GDI. As long as you take the right approach to help fight the LSPI (i.e oil, plugs, catch cans) you won't have any issues.
I have a 15 F5 and have had a tune on it since a week after I brought her home and now I have over 18K miles on her and she is pushing 24psi daily with no issues at all. There was 1 member here that had problems with his motor but that's it. Not saying we are all safe but we do have the revised parts that are stronger than the 13 velosters
