Flashing 2018 + Hyundai Turbo PCM's (KEFICO) will also be a hot ticket, Hyundai Motors America is now releasing a line of performance parts for these engine platforms.
Glad that HPTuners stepped into the Hyundai Community as the GAMMA engines have quite a good following and seem to be doing very well.
Plus there are a good amount of vendors already selling parts for these engines as well.
