My insurer (Allianz) of our Patrol wan't the slightest bit worried about it having a chip when I rang to notify. It didn't impact on our premium, but is noted as an accessory. More the issue would be Nissan warranty.
The Safari chip I have had experience with only shows a slight difference around town but when the thing is working under load it is about half a gear - strange way to explain I know, but but it just copes a bit better.
it's not like it is getting nitrous into the inlet...
If you check out the RaceChip site you will see that it is as quick as disconnecting and reconnecting a plug - as Frog posted.
