Question Car boost with button X

[zhanmusi]

Hello!

For some reason if I click X in my fivem server the car gets a boost/turbo and speeds up, I want to remove that, does anyone know what it can be?

I found that too on latest ESX Legacy. I believe it was for the admin or spawned a car with max upgrade (/car) and I tried to max upgrade using mechanic features, the turbo doesn't active at all.
