I dont see why there wouldnt be an increase. BMW pricing model sees incremental increases every year. With the changes there's no real reason for them not to increase it.
There are plenty or photos with it on the car. The artisan spirit one is rounded off and the trd one is squared. Every time they've given out pictures it was always just from a distributer and customer installation.
If the dealer says the tune was the reason for issues with the engine and voids your warranty. Ya you can go argue it in court. Pain in the ass and a waste of my money though.
Of course it's not 100% warranty loss. Its up to the dealer. But I don't have the time or want to waste my money fighting it in court if it gets to that point. If OP wants to take that chance then do it.
V1 is essentially the TRD wing. V2 is based on the artisan spirits wing. They base the design on existing products. You can even see on their Instagram they buy actual pieces first.
It's a toyota not going to work. It already says in the manual warranty work cant be down at bmw. And you would have to go to BMW to get the dinan stuff installed. Well if you dont plan in selling it until after warranty period it wouldnt matter at that point.
