Vehicle reaches only half of the max speed


I’ve made a custom vehicle and everything works absolutely perfectly except for one thing: it doesn’t reach max speed. It only reaches 60 mph instead of about 120 that I’ve set it to and speed will lower to 30 as soon as I go off road and will not go back to 60 unless I either brake or drive backwards before moving forward. Anybody knows what might be the problem?

PS: All the tires are at the exact same height and have their wheels aligned accordingly.


Nvm, I’ve figured out what the problem was.
