Small but annoying:
-When de-tuning that you don`t see the pp "live". You have to guess 95.4% and then see that you are wrong, and guess again and.. again to get the right pp
-The pp/hp information when changing oil/engine restore.
-The pp/hp information on the opponents cars before entering the race. The max allowed pp in the races are much higher than the AI`s cars. Now they just list the three different cars without any information.
