I ran stock tune with K04 just kept it out of boost. Got it through emissions and flashed it back. Car ran great.
I am not catless tho. Uni disables the rear sensor so I could't get redness either until I went back to stock tune.
YouTube is all you really need IMO. Some great content popping up and by watching you are supporting the creators.
Only movies I watch are with the kids and the GF if she wants to watch a horror/thriller movie.
Mine aren’t gauged.
Jay has some good insight on that. You can get them surgically closed back up but it won’t be the same. I’d start regular and think about the gauging.
