What kind of maintenance should be done at 30k miles?
I want to get Cobb AP, and run stage 1 while under warranty. Can I do this without getting caught if the engine goes?
What types of things should I consider getting before Cobb AP? 1 step colder plugs?
When I finally decide to go stage 2 besides TBE, what other mods would be a good idea?
Who are the main vendors also? Like the biggest, with the best variety of parts?
