i have a strong feeling that last engine(would bet on that one) or last drivetrain upgrade is making the car actualy slower

this effect i already have seen in some other car's comments, but dont know what car was it, so it might be possible

maybe if somebody could try this with rented upgrades to confirm my feeling, i can only tell by times on daytona speedway and im not 100% sure
