Having only 500 hp plus added weight and downforce I would say fully upgrade power wise and 100 the power limiter but overal a very stable tune. Good work
I have tested this car in Monza and it was very good to drive in my opinion. I did on Professional mode on Arcade Mode and I have managed to win the race in Monza. ;)
Are you sure you followed the steps in Tranny's comments? If so, maybe you've installed engine upgrades or turbos. In this case you can't meet the correct numbers.
