I will hope that if its just a software and not a hardware update then it can be done. Like Z said if Tony (TTI) can get his hands on the 2019 i am sure he will be able to copy the mapping or tell us whats the difference.

In 1st my car launches at 900rpm but doesn’t spool out of vaccum until after 2k rpm even with a plugnplay or reflash. It would be awesome if the new remap from Lexus allows the turbo to spool well before 2k

Problem with building boost earlier than that is it can cause undue stress on the rods and rod bearings. This was the case on Mazdaspeed 3’s making boost before 3K. If you did you were almost guaranteed to vent the block.
I genuinely laughed the first time I heard it.
