From my experience over the years, I have tuned my stock M5 and stock C63 and experienced noticeable performance differences along with a much more enjoyable driving experience.
None of them ever caused any long-term issues for me.
Just curious why this is not applicable to Lexus. I understand what was mentioned above, and feel that perhaps Lexus themselves are cautious.

M5 with the twin turbo V-8? C63 with the twin turbo V-8? Those are boosted engines so a tune will increase boost noticeably which results in a 10-20% boost in power. Add downpipes and they really wake up. The GS-F has a naturally aspirated engine - much harder to increase the volumetric efficiency and HP without adding boost (RR-Racing supercharger).
