3.0 GTV and Red dot mappings

Hello all

I'm in the process of deciding if I should get my gtv remapped by red dot? Has anyone had theirs done and if so what's it like now?

I've spoken to Augusto (very helpful chap) but would like to hear the differences from the horses mouth so to speak.

Cheers

No experience with the GTV 3.0's but I'm sure R*D would do a super job.
