Mega Nitro Final

Meganitro 3 version. For clarity, I'll compare it with the second version:
Second version:
1)Nitro is not for every car (after transfers from one car to another, the nitro of the first car changed)
2) The effect comes out of who knows where
3)Speed ​​is given with a jerk
4) We needed a lot of money for it

Third version:
1)Nitro is saved for every car
2) The effect comes out exactly from the exhaust (for any car)
3)Speed ​​is given by acceleration
4) Introduced by a cheat without any problems
5) Nitro is replenished at gas stations
6) When working for a long time, the nitro 'sneezes' and a jerk is obtained, and if it is even longer, it will explode.
