NO CHANGE OF SPEED ON A CAR THAT HAS A NITRO

I want to report some issues or maybe if i am the only one who sees it.

Im using a Uranus car , as you can see on the NONITRO.png you see that i max his max speed on the san fierro bridge and it came out 69kmh/kph

On the other hand , the WITHNITRO.png has already activated the nitro but the change of speed didnt increase.

I dont know if this issue works on different cars , or maybe just an issue of Uranus.

I hope this can be seen because if this nitro system wont change the speed of the car , it would be useless to have a nitro system here.

Using nitro will not increase your vehicle's overall top speed, nitro is used to lower the time it takes for your vehicle to reach its top speed.

I tried with the Infernus, they both yielded the same overall top speed but one just reached it quicker (the Infernus using nitro).
Ye Ive realized that , but anyways thankss
