SOLVED: TDU PE (2.5) issue - how to save?

[X8X8X]

Hi guys,

 

I try to install this mod:

Chrysler® 300

Installing the exterior, interior, rim, hud and sound works just fine. However, I cannot install the physics:

I chose the Challenger RT, clicked on performance pack, install performance pack, chose the one that comes with the mod. The values change. I then clicked "save car" and "save all changes".

In the game, nothing changed.

How can I fix this?

Thank you.

 

EDIT:

Solved. 2.78 works fine.
