As far as the re-flash goes, I have a 2017 so hopefully it works. I tried to find a dealership that installs performance parts but had no luck and many on this forum said any dealership should be able to install the parts, and that's mostly true.
So I did everything through the dealership I bought the car from. They sounded confident. When I dropped it off this morning I causally mentioned that they knew they would have to do an alignment, right? And they said yes, no problem.
2:30 Pacific time I received a call from them telling me they would not be finished today and that they wanted to take their time and make sure everything was done correctly since this was the first kit they have installed. ARRGGHHH! I told the tech on the phone to make sure and grease the rear control arm bushing as its harder than stock and would probably squeak if they didn't. He thanked me for the tip.
I knew I should have done this myself. I let them do it to keep the warranty and because of the MRC re-flash. Now I'm going to stress about the dame thing until I get it back.
