I was going 190km/h in 3rd gear with my max and I shifted like you guys told me at 6500 rpm and the speedo when up to 200 but wont go up and my rpm is at 4000-5000. Why is that? should I shift before 6000??

I have y-pipe, homemade intake thats is too long and maybe isnt getting enough air??

 

you have a GLE which i think is speed limited

 

i thought its the GXE. well one of those have a speed limiter and cuts off the gas when you're doing 115mph. read the FAQ and it tells you how to fix it.
