Jeep boost

I realize you can have the jeep boost using the boost config in the script. I how ever want to enable and disable boost with lua. I have tried having two scripts but i cant seem to change the vehicle script after it has been spawned. Applyforce gives it a small boost but hardly anything noticeable.

How would I make a vehicle have a boost function I can disable/enable with lua?

i dont think theres a way to enable it or disable it, but you can change the speed, sound etc… in scripts/vehicles/your_car.txt

If I can’t enable or disable it it’s not much use. I all ready have a custom script disabling. Just I can’t change scripts with out resspawning the car.
