Engine upgrade of F1 Alfa Romeo C38 failed?

[GinormousValve]

Hi everybody!

I think that I have faced a problem upgrading my new F1 car... 

Can somebody tell me if the expected Performance Coefficient for the new F1 Alfa Romeo C38 with Engine level 4, Body level 3, Breaks level 3 and Tires level 3 is 123,0?

I upgraded the engine from level 3 to level 4 and I think that nothing changed despite the engine is now indicated as level 4.

Cheers
