**** that first pic, cyl 2 issue are notorious for the 2.0 K5. If I remembered correctly you’re running a tune with colder plugs correct?? There was one member mentioned to run with 1 step colder but I for the life of me I don’t remember who that is!!!

I am running 1 step colder. Might switch to 2 step colder. Is it possible cyl 2 gets too hot cause of where the turbo is positioned? Gets really hot in that area. Might wrap it all the way down to the dp to keep temps down.
Running jb4 map 3 but recently dropped it to map 2.

Didn’t run my Lap 3 tune long enough when I had it so I don’t have an answer, maybe try running a step colder to see if it will help. Should wait up for someone that is running a tune to chime in and they can share their experiences to help you out.
