Default Vibrate on touch - intensity

Hi guys.

I'm really annoyed about one thing with my Xperia Z1 - vibration intensity for vibration on touch. I personally think it's way too long. Feels like the lenght of the vibration is set to something like 120-150ms. Is there a way to change it somehow? I have root, so maybe it's one of the system files that contains that setting?

I've set vibration length for keyboar to 35ms and I think it's perfect for feedback. Would love to be able to set it for the same value for function "vibration on touch".

Anyone anything?
