You can get followings:

You need Tekken 7 game and controller with turbo button feature.

I used MayFlash F500, but it does not have turbo hold. So I used some weight on the button.

If you use HoriPad with turbo button hold, it would be easier.

MayFlash F500 Elite


Hori FPS Plus for PS4 (works on PC too)

1) Go to Offline > Treasure Battle
2) Pick Katalina
3) Start Treasure Battle
4) Set A button for turbo and hold the button (by weight or turbo hold)
5) Just wait

Note: If turbo bottom feature is slow like 5/sec, it may not reach to top level. But 20/sec is verified working. So if there is different speed setting, it would be be better to set faster one.

• Other character or button may be more efficient. I just used Katalina and A button.
  
• Estimate time might be about 10 hour to get offline highest level.
  
• Turbo speed button matters at higher level battle. Better to use faster repeat button setting from beginning
