Problem with LFS Tweaker

Hi guys, I just downloaded LFS 6U for the great old times, downloaded LFS Tweaker, donated for all functions and I have these problems

1: If I make a turbo XRG. 2.5litre i6 turbo 1.4 bar, clutch wears. I mean every tweak more than 300hp wears clutch in 1 second.
2: In dyno mode, turbo is not working, the car is N/A

If I select automatically repair clutch doesn't work.

Any ideas?
