what turbo is it? I think the boost level of .55 bar is the stock level.

It's kkk k14. The water cooled k14. Engine is 1.6td SB. The wastegate is the fixed can type.

And 0.7 bar was the stock boost. According to the Bentley manual.

Any pics?
I didn't know they made a water cooled K14.
My K14 is "oil cooled" and the wastegate has an adjustment screw. Never messed with the screw but I did make up a DIY controller and it runs at 15 PSI based on where I set it.
