They will even install aftermarket parts but that is completely separate from normal warrantied work. I find that in places without too many reliable independent shops often have dealers that will do this. As with most businesses, they won't turn down your money.I had no idea that some dealerships even offer aftermarket tunes. If that's the case then there is probably less to worry about with Honda. Also I think Honda sort of anticipates owners trying to push the most they can out of the Type R, it's certainly a car made for driving enthusiasts. Glad to hear you've never had issues and I don't see any new problems arising with the FK8.
